Fix tool for missing tray icons!
Download it here: http://freeweb.siol.net/razor256/downloads/aswTrayIconFix.zip
Download it and extract aswTrayIconFix.exe anywhere you want.
Run it and just click Fix button. Log off and log in again or simply restart your PC and icons should be back again. The program is standalone extract&use (although it looks like installer).
Anyway, w0mbat is correct, this is Bart CD forum
