Ah I see. Yes you could use DoEvents for that. Its freeing 
the local process to read events from its own queue not 
doing anything with the NT kernel at all.

In that case it is a bit of VB cruft rather than an NT problem.

I've never encountered it even in other MS development tools
J++, VC++ etc. Certainly not in Delphi (my personal favourite 
NT tool)
