>>I just created an empty form based on the VFP base class, added 5 files to DE, and saved, then MODIFY FORM took around 6-7 sec. Removing one table at a time, the opening time decreases by ~1 sec, when there is no table in DE it takes less than 1 sec.

I try to aleviate the effect of waiting, by remembering that I am still paid for the time I wait, so I believe I will survive... ;)

Two things are still not clear to me:
1 - Is this happening to everybody, in other words this is the way it is?
From the answers I got, and are relevant (i.e. people using DE), I assume it does not happen to others, but nobody said, "yes, I repeated your test (described at the top), and did, or did not see what you see."
2 - If the answer to 1 is yes, why having tables in DE only affects MODIFY FORM, and not DO FORM?
