A lot of people have been having this problem, it'd be great if we could fix
this.

I don't quite follow.  MS Sans Serif claims to be TT, is Shell Dlg bitmap or
something?  And how would that be affected by dpi anyway?  Are dialog units
actually determined from the dialog's title font?  (That would not surprise me
in the least BTW ;-))

I'm also doing some runtime font changing stuff too (the bolded headers within
the pages), so that could come into play here as well.

I'm definitely interested in figuring out what's going on here and fixing it
once and for all.
