How can I stop getActiveScreen to throw ClassCastException?
If the current field is an instance of the screen, I can do the following:
CoffeeCard cCard = (CoffeeCard) MyClient.getUiApplication().getActiveScreen();
However, if a Menu or a dialog box is open, I get a ClassCastException in the statement foregoing, which makes sense.
In addition to checking the returned value of getActiveScreen with the instanceof keyword, is there a better way to check if the active screen is a screen?
Thank you.
What is the problem with instanceof?
for specific classes, you can use a model of the Inspector, but not for this.

Since the update to El Capitan, during the scrolling of the screen guard snapping back to the top of the Web page. How can I stop this?
Please read this message before doing anything.
This procedure is a diagnostic test. It is unlikely to solve your problem. Don't be disappointed when you find that nothing has changed after you complete it.
The test is intended to determine if the problem is caused by a third-party software that loads automatically at startup or logon, by a device, by a police conflict or corruption of system files or some system caches.
Disconnect all devices wired except those required to test and remove all the expansion cards from secondary market, as appropriate. Start in safe mode and log on to the account of the problem.
Note: If FileVault is enabled in OS X 10.9 or an earlier version, or if a firmware password is defined, or if the boot volume is a software RAID, you can not do this. Ask for additional instructions.
Safe mode is much slower to boot and run as normal, with limited graphics performance, and some things work at all, including an audio output and a Wi - Fi connection on some models. The next normal boot can also be a bit slow.
The login screen is displayed even if you usually connect automatically. You need your password to log on. If you have forgotten the password, you will have to reset it before you begin.
Test in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and make sure you always have the problem. View the results of the test.

How can I stop Firefox change my title bar?
It's frustrating and time - there must be something I've missed to make it stop. With each and every update - Firefox decides I want really different buttons in my bar tools/title bar. It's just crazy, if I wanted the Hello button I would add it. Even with all the other buttons it think I want. How can I stop?
The title bar is disabled by default. Please provide a screenshot of [with an arrow to] that you refer.
