Not directly related to the v8 beta, though perhaps something that can be solved in v8. I've installed the 3CX Voip Phone v3.8571 on Windows 7 Ultimate. It works okay, though the GUI gets messed up after minimizing/maximizing the screen. It shows the default Windows border around the 3CX application and moves all the contents of the form in a way such that it makes the complete application useless. Only way to get the GUI back to normal again is to shutdown and restart the application. Minimizing to the tray and restoring it won't work either. Perhaps something you guys can look into and fix in the next v8 release? If desired, I can send you a screenshot of the messed-up state of the app on request. Thanks!
