I've been experiencing since the installation of Windows XP SP2 on multiple machines with the ATITool Tray Icon disappearing upon load at system startup. Sometimes it's there, sometimes it's not. Enabling or Disabling the "Hide Inactive (tray) Icons" WinXP menu option doesn't have any effect. The only way to open ATITool after it has loaded is to go through the start menu to open it again. I have "minimize on close" selected in ATITool. When closing ATITool, you see it make the motions of minimizing to the tray area but no icon is displayed. Any ideas?
