*VWMFix essentially switches on HideTaskOnSwitch for windows owned by the window you list, so no surprise that it didn't work. :( Maybe a *VWMUnfix...

I do have a version of RabidVWM that works with tasks' per-desktop mode, but I think I was waiting to hear back from jugg to confirm that I haven't gotten any of the messages wrong. (ie, different... already had to fix it once to match bangvwm)
