Thanks, David,

So was I leery - but I forgot to do it before. However, the Dr. Watson occured BEFORE I did the SP3 upgrade as well as after.

My next thought is to uninstall VS6 and VFP5 and reinstall just the VFP5 to see if it changes things.

Or, maybe I'll just tell a coworker to make any changes in the form that's being a problem < grin >

It runs OK if compiled, and (very oddly) it will run OK when called from 2 forms but not when called from 2 others. In the latter cases, I get an 'access denied' message from one form and an 'out of memory' error from the other.
