mallet wroteain't got this here, on xp sp3
Did you install 2.0.0.281 on your system with no older jv16 files or folders present at the time of the 2.0.0.981 installation....in other words a completely clean/fresh installation?
When I assisted my brother with the installation of PT 2010 B970 on his XP-SP3 system a few weeks ago, I had him completely remove PT 2008 (all files and folders) prior to upgrading. After installing PT 2.0.0.970, "memsearchwords" was present in Clean and Fix search words settings. I did not report this as a bug at the time because of other things taking priority.
