>>>I had this problem that was a bear to figure out. My problem that the pointer from the .DBF to the corresponding place in the .FPT was screwed up. Pack and Pack Memo did not help. To fix it, I opened the table and did a COPY TO TEMPFILE (WITH CDX), verify the contents of the TEMPFILE, close and delete original .DBF and .FPT. Then rename all the TEMPFILE components. IF your table is linked to a .DBC, then I would ZAP original then APPEND FROM TEMPFILE in order to maintain all your table properties.

But with my experience with NW, I would really doubt any problem is with that. Were the tables originally VFP tables under Win3.1? You may still want to try the copy option.


We did the copy thing the other day. Still too early to say if it fixed things.
The reason I bring up Netware is two things:
1) We just upgraded the office to Win95 and the users are reporting the
application is now sluggish. I suspect the Win95 drivers are slower than
the old drivers we were using under Win 3.x.

2) Past problems with Novell drivers and FoxPro.
