Thanks for the video. I saw that you removed from the bottom dock bar the voodoo-x and iGame. I wonder what is the error they give to you. They both use MUI, and I guess that this should be installed as part of the ClassicWB distribution. Did you try to use SnoopDos to see what errors you get?
Possibly, because you do not use the User-Startup of the ClassicWB, you miss the MUI assignment that is happening in there. That's why the MUI is not working. That's why these apps are not working.
