there is very annoying behavior:
Application pops up dialog box [like attached - #1]. Window seems to be active, so I expect that pressing Enter [because [OK] is? focused] I will be able to close this pop up.
But it does not work. I have to close it by mouse.
What is more interested- it seems that behavoir depends on kind [source?] of displayed message. I’m able to close message #2 by keyboard without any trouble.
