I just installed Houdini 9.5.230 apprentice on my PC (run Vista x86 Sp1 with a 8800GTS 177.92 driver. Houdini just freeze if the Logitech Logitech QuickCam service (lvsrvlaucher) is running. I guess Houdini GUI used the cygwin library and those two are not compatible if I'm correct (may be?). Any help ?
