Nadya,

QueryUnload() is called when the X is clicked. By time Destroy() and Unload() fire there are no controls left they've already been destroyed. The only time I ever put code in Unload() is to RETURN the value for a modal form that is launched with do form xyz to theReturnValue. Is there a particular reason you are calling Hide()?

I tried Destroy, Unload, other - all unsuccessfully. If I close my forms using special close buttons "Cancel" (thisform.hide()) all work, but if I close my form using the right cooner close button, my form unloads (I mean my second form, which I want just hide not unload):(.

Now I place tableupdate() into unload method of my form (it was before in release method) and I don't see this error. But I am not sure that this is a solution.
