>No, it doesn't seem to do the trick in CodeMine, as it causes some other items you have to deal with. But thanks for the help.

Well, the basic idea goes something like this:

* Method: QueryUnLoad()
* Will be called when user presses "x"
if not (DoDefault() and AdditionalConditions())
  NoDefault && Do not close the form
endif

Perhaps the form classes in CodeMine call some other method from QueryUnload(), which you can use instead. If this is the case, perhaps you don't have to use NoDefault; instead, adapt to the structure of the function (probably RETURN .F.).
