Ausatco,
Fascinating thread - glad you got to the bottom of it, or so it seems.
Just curious, as I don't run XP, did you change from FAT to NTFS when you reinstalled XP ? Is there an issue there perhaps ?
Brings more questions to mind wrt paging - does Win2K work in the same way ?
It's very late/early so I may have missed something in the MS reference. I'll re-read it.
Cheers and great work !
