What difference is there between
if form.showModal = mrOK
and form.ShowModal (MyCallBack)?

I get it.

If I have a modal form that contains a frame (containing a dbgrid), what happens when the modal form is closed?
Is the frame, also shared by other forms, available again?

It happens to me that closing the modal form, and opening another non-modal form containing the same frame, the application raises an exception on the frame.
Can the problem be connected?
Thanks
