 problems associated with the GUI sending events to deleted windows.
 
-Don't create a window on the stack, because this will interfere with delayed
-deletion.
+In general wxWindow-derived objects should always be allocated on the heap
+as wxWidgets will destroy them itself. The only, but important, exception to
+this rule are the modal dialogs, i.e. wxDialog objects which are shown using
+wxDialog::ShowModal() method. They may be allocated on the stack and, indeed,
+usually are local variables to ensure that they are destroyed on scope exit as
+wxWidgets does not destroy them unlike with all the other windows. So while it
+is still possible to allocate modal dialogs on the heap, you should still
+destroy or delete them explicitly in this case instead of relying on wxWidgets
+doing it.
 
 If you decide to allocate a C++ array of objects (such as wxBitmap) that may be
 cleaned up by wxWidgets, make sure you delete the array explicitly before
