If you run the test case below and perform all the normal actions
on one of the JInternalFrame's, i.e. open (done by clicking the add
button), close, minimise and maximise, give one focus and then give
something else focus (activate/deactivate) you will see the following
events are not fired:

DeActivated
DeIconified
Opened

The deactivated and deiconified events are generated for Windows NT
(still no opening event) but are definitely broken on Win 95.

This occurs on NT and Win95 under JDK 1.1.6 and Swing 1.0.2
