Well I gave in. Refreshing Windoze did no good. Completely removing and reloading poser did nothing but lose my sketch presets (The one thing I forgot to backup) Removing QT and WMP and all Compression codecs and reinstalling all those had no effect but to waste time. I even installd windows into a new folder (In an attempt to aviod a complete melt down. No Dice. Backup every thing and wipe out an otherwise health install of windoze. It now works again. How long though? Remember what caused it to flip was that Poser locked up during an animation. I'm sure there is some damn RSR file some where that got screwed up but nobody seems to know where it is. I sure hope to hell that Poser 5 doesn't have RSR files or at least is able to maintain them better. Remember folks all those "Out of Memory" errors are just screwed up RSR files. Delete the offending RSR and it will start working again. I just wish I could have found the one taht was ticking Poser off this time.
