I now tried on my standard XP machine and do not see any adverse
effects with file, directory and font dialog boxes.  Maybe it's
related to the fact that I have "focus follows mouse" plus
"autoraise".  Could you try with such a setting?  I am very reluctant
to change mine becaue I have some additional mouse software working as
well.

What was the more or less precise rationale for this unless it was
pure experimenting (in particular the SWP_NOACTIVATE in the first
call)?  The patch does not have any (adverse) effects here so if it
solves the problem for you, I see no problem applying it.

Can you send me the code you tried?

In w32_dialog_in_progress I tried to solve a relatively simple
problem: When a frame is in the TOPMOST group and I start a dialog,
that frame would obscure the dialog box.  So I temporarily remove the
frame from the TOPMOST group and move it back when the dialog ends.
