The Radeon Software 20.4.2 executable on my Win7x64 SP1 displays only window title bar with icon and 3 buttons(min, max, close). It does not handle mouse events at all.
At the same time, all the software i use have no problems with their windows and controls at all. So, the driver configuration tool must be as lightweight as possible and have no dependencies at all(nether m$ .NOT, media players, internet explorers, abdolbe AIRs, etc.) to be able to run on EVERY Windows where WinAPI is available.
The bloatware depending on external stuff like dot-NOTs and interacting with youtibes, youkukus, facepooks and so on must be a) separate from hardware-related subsystem and b) absolutely optional to install.
