When I have only a single tab/window open, I used to be able to use the command-W to close. All of a sudden, it doesn't let me. No idea why that might be?

I tried to reinstall the version 7.0.1, but that did not help.

same thing here. When I disabled it Evernote Clipper Add On I could close a new tab.
