Sorry I wasn't clear.
The startup popups that USBSR found no drives and then that it found drives (the image in my post) appeared automatically
without hovering my mouse over the system tray icon.
I use the word "appeared" instead of "appears" because I solved this problem but am now confused why USBSR still loads automatically.
To explain, I decided simply to disable USBSR from loading at startup thinking that if the program doesn't load, none of it's components will either. So I unchecked Startup>Run on Windows startup under Options:General. However, USBSR still loads (at startup) but neither of the popups appear.
In summary, USBSR now behaves as I want it to (loads at startup with no popups) but why does it still load even though I've unchecked that option under Options:General?
