Hi,

>>This is a multiuser app and the issue arises at run time. How can I implement debug code on this type of environment?

If it's only seems to be occurring when running from an EXE then I guess you just need to get more information into your audit file. If I read your original post correctly then it's definitely the InterActive() event (rather the ProgrammaticChange()) which is detecting the changed value? AFAIK there are only four ways this gets fired:

1. User Interaction (which you, or at least the user, say is not the case)
2. Code elsewhere which calls the relevant InterActiveChange()
3. Code which stuffs the keyboard while the control has focus.
4. A haunted computer<g>

If you've got VFP8 you could use the Code Reference tool to look for any occurrence of the second possibility.

I'd consider adding code to track the record number of the relevant table and also save ASTACKINFO() when you detect the change in InterActiveChange - that should help tell you where it's coming from.

HTH,
Viv
