Hello all

I have random problems with GUI controls. Sometimes with DEBUG or RELEASE, when a control is destructed an EXCEPTION_ACCESS_VIOLATION exception raises. This happens in ScatterCtrl.
For example, function ScatterCtrl::DoShowEditDlg() calls PropertiesDlg(*this, itab).Run(true) opening a dialog.
Sometimes, when this dialog is closed, this errror raises. The function call stack represets basically destructors:



It is like there is a problem in the destructors order, so that in this case, when ColorPusher destructor is called, parent controls has been already destructed.

I have seen that many or maybe all GUI controls have virtual destructors. Maybe it has no sense but, should GUI user controls destructors have to be also virtual?
