Question : drop down list in access not always working

Database created 2 years ago. Form based upon a table. I put a combo box at top to allow user to look up a record by name (almost 3000 records). Everything was fine until a few weeks ago, when the drop down box was no longer functioning.

Made a copy to test on my local machine. After re-linking tables (database is split), it works fine. Put a copy on a shared drive (and re-linked). The drop down function when I run from my machine works, but does not work for user from her machine. I put a msgbox in the code for the afterupdate event, and msgbox does not pop up (doesn't look like it even fires the code). Did click on enable the content when DB opens.

Any suggestions?

Answer : drop down list in access not always working

Is the other user running the front end from the "shared" drive, or was this just a test.  I would strongly discourage letting users run the application from a "shared" or "network" drive.  Every user should have their own front end.

What version of SP of Access are you using? Does this other user have the same system configuration as you?

Have you tried decompiling the code, then recompiling it?
