Well all of the sudden my Poser Pro is running incredibly slow... this is really bizarre and all I can think of is that I was away for a few weeks and now I'm back on my main work machine and for some reason it takes like 10 minutes to load MAT files and many props... even extremely simple ones. Now I did a complete wipe of Poser and started over, installed Poser4, then 4.03, then Pro Pack, then the memory upgrade (I have 1.5 GB of RAM). Service Pack 3 for Poser Pro won't install on my system it says "no valid poser pro installation found" which is ridiculous, but oh well their loss- I hear it does that to just about everybody. Even after the total reinstall Poser is performing extremely slowly. I have a 3.2 ghz system with a 400 mhz board, and right now it's almost too slow to even be used at all. Anyone have any idea why it might be running so slowly or what system tweaks I might try? Thanks, Brian
