I have been having problems with GEM and PD 3.7.1 under win2k. The program crashes, usually after I stop rendering destroy the gem window, create it again and then start rendering. The program is almost entirely unuseable unless I turn off antivirus protection and firewall. Some times when I try to close the Gem window via the task manager it says it is going through the debugger. I have used several different builds of GEM and pd 3.7.0 then 3.7.1. Does anyone know of a stable build for win2k? It all worked so well under win98se, but I guess things are a little different with NT architecture.
