Arto,

If I understand well, you want to intercept window events.

Although possible in theory, I think this would be pushing it a bit

My aim was to provide a callback while a dll call was running. This has been tested and no problems so far.

What you are after is imo interrupting vfp whilst executing statements. And I fear for crashes ...
Could (not necessarily would) work ;-)

update
Cannot handle CallNextHookEx(), ie a vfp function cannot do that.
That would be a special case, ie to be treated differently
