ZAPro F***ed up my WinXP pc :yell installed it and wham! My machine freezed in startup ( something about windows shutting down to avoid hardware damage??? ). I had to use diagnostics mode (F8 when booting) to clear my system. Note that this was first time in nine years I had to use F8 booting:mad BTW. It also cleared most of proggies away from the control panel/uninstall window - software is still installed I just can't uninstall it normally :?
I now use Sygate, and I am very happy
