I can't say why this would be the case. Extensions do work (I tested one for
someone else only a few weeks ago). Try turning on debug (use pvengine.exe
/debug and look for c:\povray.dbg after pvengine has exited.)

If this still doesn't help, then compile the povray for windows source and step
through the initialisation code (LoadGUIExtensions () in PVGUIEXT.C).

If there turns out to be enough interest in GUI extensions I will establish a
group for it.
