Ah...painless to install and painless to run.
Ticks over at 12meg of ram and 0% CPU....frantic mouse-overs get that to over 80% but instantly back to 0 at rest.
LiteSTEP in XP doesn't appear to have any qualms about it at all....recycling still works, no crashes or shell-loss.
My only 'odd bit' is the grey background to the static icon bar....doesn't enlarge vertically to include the magnified icons, but extends laterally to suit them.
This is 'slightly' transparent, partly showing the wall, etc, but would be ideal if 'invisible'.
This could just be some odd setting in Exploder [the shell I don't use]....
