Al, I wonder if it has to do with the dual audio streams that are now in effect, with the speed of the machines. There was a noticeable resource usage increase due to the tx and rx audio streams. Just a guess. On my 2.0 ghz machine, it could only run the later SVNs (no CAT or VCom running) when I boosted the memory to 512K and then it ran at 50%.. 1 ghz Celeron might be alittle taxed.
