Hi jill,

In my case i did identify this was a problem when I did somethin like "THISFORM.TextBox.Value = cSomeValue" while the textbox was bound to a datasource. This was something I inherited from an old application written by someone else.

Also, when sometimes when an error occurs on such form this error could show up when trying to close the form.

Anyway, I'm convinced this is a VFP bug, but I was not able to get some repro code yet.

Walter,

>Did you ever find a solution for this? I have almost the exact problem...same in VFP7 and VFP8. The form, Cases, had been working. Now when I close the form i get the alias not found problem (on a view)...I'm using a private data session. The view is open when the "Close" button is clicked, and the error is raised on the READ EVENT command.
