Mods have slowed the database

[Tony Miller]

All
I made some changes to A2000 mdb whilst working in A2002.I did not
convert the file format to 2002.Now it is released some forms that I
didnt touch are taking 15 secs to open whereas in the original they
took 2 secs.
The database compiled OK
I tried deleting and recreating indexes to no avial
Compact and repair no effect
It uses linked tables to a backend

Any ideas

thanks for the earlier comments i received
THe problem seems clearly related to the access mde rather than the
opeating systems as I first thought

It appears that Access tries to be too clever and caches information about
the linked tables. If they are not exactly as expected, the caching results
in much worse performance.

Tony Toews has details on this and other performance issues with Access 2000
and later at:

Tony Toews site a great help on performance FAQ you dont read in the
