Hi Bruce,

I tried the following explicit syntaxes as tests:

THIS.COLUMNS(1).WIDTH = THIS.WIDTH - THIS.GRIDBARS

resulted in same error;

THIS.COLUMN1.WIDTH = THIS.WIDTH - THIS.GRIDBARS

resulted in "Unknown member COLUMN1" error.

Yes, everything "appears" :-) defined in the debugger when the error occurs.

However, the form Resize event fires during the shutdown process. If you read Stephen's reply, I think he may be on to it. Probably has something to do with the destruction of the objects and/or the order of destruction when the form is shut down, so even tho the objects are "still defined", they must not be "seeable" when the Resize is fired during shutdown. As Stephen suggested, I guess I'll just put a flag in to test when the form is shutting down.

Thanks,
Bill
