Yes, this is one of hte problems with dialog-based apps. There is also an MSDN article on
how to use keyboard menu shortcuts, but I can't find it in the latest MSDN (while they
still retain Win16 articles, many of the useful other articles seem to get purged. There
is a trick you have to do to make the shortcut keys work. But I spent a fair amount of
time doing MSDN searches and couldn't locate it. And I know I've seen it there.
