Are you using BlackIce firewall with application's protection on ?
Then, you might have problem when updating your theme.rc to make litestep load new modules :(

Generally, BlackICE will popup a box saying that Litestep.exe is trying to load an unknown dll...
Generally, in that case, you just have to check the box and click "OK"...

But if you're using ckhotspost too, litestep will freeze and the BlackICE box won't react

This probably only happens with the mouse hook style. It installs a system-wide hook, so mouse events sent to blackice will be redirected to ckhotspots, which blackice probably intercepts, etc.... (technically, it's probably the ckmousehook dll)

Yes, I have

But, currently, I can't test if it works without it. I'll let you know...
