Scrolling, pinch and zoom does not work in touchpad DM4-2015dx
I did a clean install of Windows 7 Ultimate 64 - bit edition on my new laptop HP Pavilion DM4-2015dx from Best Buy. I was able to find the drivers for all devices except the touchpad. Currently, the touchpad functionality is limited to basic operations. I can't scroll, pinch zoom, etc. I tried the latest drivers of Synaptics Touchpad HP and Synaptics site without a bit of luck. The touchpad is simply recognized as generic "Standard Pointing Device."
When I go into deivce prperties for the touchpad I see only the options for assignment of the buttons. There is no option to activate the rollers vertical or horizontal, pinch zoom, etc. Help, please!
OK, so I found what the problem was. Initially, I assumed that the touchpad is a Synaptics touchpad. It is NOT the case. The touchpad is "Alps pointing device". The drivers installed with HP Pavilion DM4-2015dx out of the box are dated 18/02/2011 version 7.206.1717.117 as Alps pointing device. These particular drivers were not found on the HP website. However, there are similar drivers of 2010 that work very well. Here is a link:
Alps Pointing - device Driver (2 channels)
Without the right drivers you will also find expreince the cursor jump effect where the cursor will jump at random on the screen locations as you type. It has nothing to do with the user touching the touchpad. It's just that the generic touchpad Windows drivers are NOT compatible with the Alps touchpad.
A final word for HP. PLEASE post all drivers for HP Pavilion DM4-2015dx on your Internet site, as well as ALL the HP utility.

Pinch and Zoom does not not Android V26
Hello
I am currently a folio of construction and hoping to take advantage of the new support of pdf to V26 (for Android tablets). I updated the tools, folio Builder and content viewer Adobe to V26. I downloaded successfully three articles with pdf format selected. The first article works fine (I can pinch and zoom in). The second and third items however do not pinch and zoom. I double checked my settings and even reloaded these two articles, and they do not always work. I'm doing something wrong?
Unfortunately, pinch zoom on Android & PDF does not work at the moment, when the article is set to Swipe Horizontal only. In addition, pinch zoom & PDF does not work for items in scroll smoothly on Android or iOS.

PDF of pinch and zoom does'nt work correctly in the viewer content v25
Hello world
I wonder if anyone has experienced the same problem when view PDF-folios in the new v25 Viewer update: when I do the typical pinch & zoom gesture on my PDF-folio-case nothing happens. I type the first page so it will zoom in and THEN I can pinch and zoom in as usual.
I tried with folios build for v25 as well regarding v24: as long as I open them in the viewer content v25 this "bug" will appear. I have never experienced such a problem in v24 content viewer: all my PDF folios could get pinched and zoomed immediately without typing on it first.
So, it is already a known bug? And if so, Adobe is working on that, yet?
Thanks for any answer!
It is a question, and he reported to the team to fix in our next release.

Scrolling Alt to zoom does not work in Acrobat, why?
I have used this feature all the time before, but it no longer works. Why?
I have Mac OS x 10.10 Yosemite and use a Logitech mouse. Lates versions of all the CC apps.
Hi Stevenjordan,
Apparently, this problem only affects the manufactured Apple mouse. If you use any other than Apple USB mouse it should work fine,
I am able to reproduce this behavior with Apple Magic mouse and Apple's USB mice, but not with a mouse Microsoft USB's.
We are currently investigating this problem.
Kind regards

The date and time does not work.
I have an iphone 5 c.
The date and time does not work. This is the second time. The first time was about 3 to 4 months again and now again after upgrade to iOs9.3.1.
Even after trying to change it manually, time slows down or stops.
Everyone has problems with their date and time?
- Try a forced reboot: hold down the House and on the buttons until the unit turns off. Ignore the cursor off if it appears. Once completed, if it does not start on it own, turn off power with the key On. In some cases, it also contributes to double click the Home button and close all applications before restarting.
- Restore factory settings (no backup)
- Make an appointment at your local Apple store to have it checked.

pages started freezing, force to quit and restart does not work
Try to do the homework, no good with computers. I used screen split pages with safari, then I'll click to pages and the cursor does not blink, and I can ty click on something, but nothing helped. I even try to click in Safari and who does not work either. I have to then press the task or what you call it, force quit applications, then restart. It started just randomly and really annoying, see I need to deal with all my classes AP. Pages for this when alone as well.
Hello ElliottRadovan,
I understand that the Pages and Safari sometimes appear to hang when switching between the two. Fortunately we have some articles that detail how to identify and correct the source of the problem, restore stability to your Mac.

Is there a way to change the font size in the comments to a readable/superior police box? I went to Keynote > Preferences > General and tried making it bigger, and it does not work. Keynote 6.6.1 thanks.
The fonts themselves, or one of the font attributes cannot be changed; (size, color, tabs or alignment)
Although it would be very helpful to change the font size, in normal circumstances, this should not be a problem; comments are designed as a personal note by the designer and should only ever be seen by them.
