I originally had my routine patch SystemTask and I rarely experienced any
trouble, however once I was using DesignStudio when my INIT's dialog
popped up (anouncing an appointment).  When I dismissed it and then pulled
down a menu, the menu's font was Eurostyle Bold.  After pulling down the
menu again it was fine, but it did seem odd.  Anyhow, it didn't seem to
be at all destructive, so I might just continue to use SystemTask.

BTW, if I call GetNewDialog and provide storage for the DialogRecord as
well as a handle to the item list, will it actually allocate memory,
thereby risking a memory move?

Thanks,
