wx3 and it was causing an issue with focus.

+// I added this to "fix" bug #334.  At that time, we were on wxWidgets 2.8.12 and
+// there was a window between the closing of the "Save" progress dialog and the
+// end of the actual save where the user was able to close the project window and
+// recursively enter the Save code (where they could inadvertently cause the issue
+// described in #334).
+//
+// When we converted to wx3, this "disabler" caused focus problems when returning
+// to the project after the save (bug #1172) because the focus and activate events
+// weren't being dispatched and the focus would get lost.
+//
+// After some testing, it looks like the window described above no longer exists,
+// so I've disabled the disabler.  However, I'm leaving it here in case we run
+// into the problem in the future.  (even though it can't be used as-is)
