Used Poser extensively last weekend - no problems. On Sunday night, installed Quicktime7 (+itunes) to use a new codec. Result: Poser6 won't run - halts during load or halts during menu operations or exits on disk file operations. Have reloaded Poser6 runtime from backup and also have reloaded Poser6 from scratch plus SR2. No joy. I have just done a WinXP restore back to a couple of hours before loading Quicktime - and everyhing is working perfectly. Makes me think that a Quicktime7 codec or dll may be incompatible with Poser6. Cannot find this case by searching this forum, but I thought I should let you all know. David. (martindj)
