I installed Windows 7 64bit version a few days ago and I have a problem with Minimize, Resize, Close buttons. When I am opening the new window, browser etc. buttons are visible, but when I am hover (in fact onMouseOut event) they are disappearing. I didn't erase also any drivers, however I installed the newest Nvidia graphics driver. It is still the same problem.
I thank for the reply. I apologise for my slips of the pen.
