Most VFP properties seem not to create an event when they are changed by VFP.
A real shame, and I reported it as a bug.
I wanted to use _screen.formcount so that whena new form is run I can bind to it and translate it.
But it doesn't fire events, and I have to put RAISEEVENT(_screen,"formcount") in the INIT of each form.
So I might as well call my own code there :(
