What version of Windows are you using, and if you're using Vista or Win7 are you using Aero?

I am using Windows 7 x64 RTM with all the latest updates applied and Aero enabled.
I am using TeamViewer 5.0.8421 and it appears to be working perfectly for me. I can set a Compatibility option to remove the TitleBar Buttons and they disappear. The buttons are also functioning as expected for me. Can you provide more information that may be relevant to help me reproduce the issues on my machine? Thanks!
