Hi guys,
sorry for the delay.
The problem is reproducable now. Whenever I quit MC with a maximized window (which is mostly the case), this happens with either skin - and currently I am only using one that ships with MC.
Please see screenshots below:
Noire Skin:
Aruba Skin:
The black "border" around the pictures is already my desktop, so you can see, the window just seems to be cut.
I did not install a pimped video driver, but the one directly from NVIDIA home page and keep it up to date frequently. However this problem persisted several complete OS re-installations!
My Graphic adapter details are the following (as shown in Windows 7 control panel):
NVIDIA GeForce GTX 260
Driver Date: 09.07.2010
Driver Version 8.17.12.5896
Maybe important to know: I am using a 64 bit machine and of course the 64 bit version of Windows 7.
