Interesting. I am opposite. It connects to the database when they open the compiled app and it stays open until they close it.

I've been applying a connect/disconnect to each app in my external form file (main menu) which is compiled, for some time. However, a user reports a "freeze" of a form, or, navigation between applications form time-to-time (for example, no issues for a week, then just today, 2 issues). Looking to my code to see where/if it can be improved... Thank you, Brad Davidson -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of A.
