Drew,

I thought I was but when I tried it a second time using a dummy form instead
of my main form it worked!!!  Thanks a heap!  I chased this one a couple of
days.  :-(

Are you maintaining the link to the backend?  It's very easy to do.  Create
a table (anything will work, but I commonly use tblLink), just one field, no
data necessary.  Then, in your FE, the VERY first thing you need to do
(after you verify the links are good), open a form bound to that table, in
hidden view.  That will create and maintain a link to the backend, and
should speed things up quite a bit.

I have an A97 BE with multiple A97 FE on a Win 2K server.  The Workstations
are on 2K as well.  When I open the first user's FE, it takes 5 seconds.
When I open the second user's FE it takes 20 seconds.  It doesn't matter
which workstation is second... its always 20 seconds.

The time difference seems to lie in a section of code on my main form that
does 7 lookups and makes tabs and other controls visible or invisible
depending on that user's parameters the employee table.  I can optimize the
code and reduce the time considerably but I am wondering why this is so...
and what performance is it costing me in other areas of the program?

Also, I have used the same technique at another customer that I have not
tested as thoroughly but uses Citrix.  Their database takes about 80 seconds
to over the network but only 12 second on Citrix.  Is there some file
locking going on that shouldn't be?  What's the deal?


Gregg
