Problem with marking/selecting text in win 7 x64

I had no problems with windows or anything,everything was fine, until this morning when i started computer and in Google Chrome marking text became nightmare, either it isnt marked at all, or it just mark last couple of letters on last word...sometimes even pressing back or forward button isnt recognized, or any other button on browser...

btw when i booted win this mornin' i got updated flash player...

And then i tried to mark text in windows= SAME THING...its so annoying

Is this familiar problem? help please

Same problem in IE or Firefox?
Or just Chrome?
