Yeah, regarding the FAQ and the CPU-Usage/Plug-in thread, I starting having this 100% CPU (well, single core anyway) usage problem with 220.127.116.11.
This was the same under both XP and Vista. The solution was to disable the Acrobat plug-in ("PDF-ActiveX"), so you could try that, mythprod.
I do admit that this is odd because 1.) I doubt the plug-in itself has changed in a long, long time, so why the sudden malfunction? and 2.) Wasn't this issue with the Acrobat plug-in resolved eons ago, like back in v.8.0 of Directory Opus?
