Hi,

My user are having this kind of error from Dr Watson for Windows NT:

Exception: Acces violation (0xc0000005), Adress: 0x0c005043

I'm able to reproduce this error in a specific situation which is this:

I open a form, I miminize the form, I close the form, I reopen the form, then bang, the error occurs. Note that the error does not occur if I don't miminize the form...

I did some investigation and I found that if a put "wait '' time out 1.0" in formset.release() AND "wait windows 'Unloading please wait...' timeout .1" in Formset.unload() then no error occurs.

Reducing the time out to 0.5 second brings the error back (at least on our slowest computer).

Additionnal information: It occurs only with big complicate formset, not with small formset or single form. We run our application on a NT netware with NT server and NT workstation, in conjunction with MS SQL so the dataenvironment contains many external views plus some additionnal cursors ceated in coding.

Questions:
1- Is there another workaround for this problem (I don't want to redo the forms...)?
2- Is there something I can do somewhere else to reduce the timeout in formset.release(), (i find 1 second being too long).

TIA
Diane Robitaille eng.
