Update to .1203 through the GUI has caused massive slowdown problems for me. Getting prolonged disk thrashing which renders everything onscreen unclickable for periods of about 30s, sometimes longer. Disabling the file system scanner speeds things up noticeably.
This is on an XP SP3 system, 2Gb RAM, dual Xeon 2.8Ghx Processors.
Is it possible to downgrade to the previous version temporarily?
Edit to add: I'm not running any disk management, defrag, or other AV software.
