FYI
If you have Norton/Symantec as your virus checker on downloaded files, it will quarantine SkyTrack and flag it as WS.Reputation1. This is NOT an actual virus. This is Norton's designation for a file that it cannot find in its database, because of low usage statistics. Not surprisingly, ST 1.5. is quite new; hence low usage. Not an real problem, but you will have to restore it from quarantine to install.
Thanks to Brent for his effort on ST!!
