Any chance to check ATT with your board on XP? I think this is because of Vista. And about monitoring graphs. Nothing happened when you click menu item??? How it can be? There are no prevent code from opening monitoring window. The only thing can happened is - monitoring window opened somewhere outside the desktop! This window remember its last positions. Run regedit.exe and navigate to this key HKEY_CURRENT_USER\Software\Ray Adams\ATITrayTools then look for values MWLeft and MWTop - This is screen coordinates of monitoring window.
