Cause of the problem : the WM_CHILDACTIVATE message is not
sent anymore, so the mdi children are not activated (caption does not
change color, more annoyingly the active child is not set). The problem
can be seen with Eudora or ForteFreeAgent.

Using this patch :

seems to fix the problem. It may be too simple though :-)
