Spy Sweeper "ICON" Issue In XP Home

I'm using Windows XP Home with SP2, and it is working flawlessly! However, I have an annoying problem with my Webroot SPY SWEEPER program (without antivirus.) I've contacted Webroot concerning this problem, but they've stated that it is a Windows XP issue. Also, my Spy Sweeper utility is currently up-to-date. The problem deals with the Spy Sweeper ICON. Each time I boot-up my computer, the Spy Sweeper icon does not remain hidden (behind the round blue button with the white arrow on it) which is found in my system tray. Incidentally, all of my other software icons are always hidden behind the round blue button in my system tray, EXCEPT for the Spy Sweeper icon, when booting-up. In order to hide the Spy Sweeper icon, I must always re-configure it in XP in order for it to remain hidden. Then, my Spy Sweeper icon will remain hidden (behind the round blue button) until I completely turn-off my computer. However, the Spy Sweeper icon will fail to remain hidden, and thus re-appear, upon rebooting my computer. Does anybody know of a way to completely rectify this annoying Spy Sweeper "icon" issue?
