Well heres a ray of hope. I may have solved the program freeze issue by following the info on the Smith-Micro knowledge base. I erased all the temp files and ran windows disk fix. I'm crossing my fingers but no crashes so far. I also installed a few new items in the Poser root folder. and the created an image with only those items found in the poser folder[no external runtimes]. I rendered with the image, saved the image, restarted poser and Voila' no errors in loading. Maybe poser 7 and Vista don't see eye to eye on who gets accesss to what. Still looking for any and all input.
TIA
