Al,

1. The DNS question: The machines in question are in a WinNT domain, and one of the machines in question is a laptop that is not currently in the domain. Do you still think that pursuing DNS is appropriate?

2. I tried turning off write caching. And the error that I am seeing changed. In fact, that has been one of the confusing thing about this bug. When I do something like add some debug output, the error changes. But, this is very specific. The original error I had was in the txtbtns.setallprop method. This is the routine that goes through the entire form and enables/disables all of the controls. I was seeing a "Not an object" message from this method during form initialization, i.e. when the form was starting up. However, if I change something, that error goes away, and I get a different error but, from the same control, NavBtns. This time when the form is shutting down. An error from NavBtns.Destroy()about an alias not found.

If this were a C/C++ program I would suspect an errant pointer. Or maybe a problem with insufficient stacksize. Seems to me that the code is getting corrupted somewhere.

I certainly would appreciate any further thoughts on how to debug this.

Thanks,
Jim
