Under Preferences/General I have When AIDA64 starts: Hide Main Window (minimize to System Tray) selected. When my computer starts up the main window still opens and I have to manually minimize it. This also sometimes causes AIDA64 not to appear in my G19 LCD. If I close AIDA64 out and reopen it will show in my LCD, but the main window still opens and does not minimize to the system tray. I'm using Windows 7 64bit with the latest version of AIDA64.
