invisible dialogs in xp?

[DC]

an app I've been working on was done, or so I thought...
I have 98, but when run on an xp machine the options dialogbox is invisible... the controls show up but that's it...
and the about window doesn't dissapear when you click it...
all this works fine in 98,
any usual suspects?
it's late now so if I need to post the code it will be tomorow or the next day...
just wondering if I may have overlooked a difference thing that is well known...
thanx,
DC

DC,
when using  dialogbox's you have to make sure you
return a 1 in your dialog proc when it exits.

in 95 and 98 you can get by without this but
not in NT machines.

It's important to follow the register saving conventions.

Some of the Win98 versions of API functions will switch between 16-bit and 32-bit code to get their work done. When that happens, you may get lucky and be protected from violations of the register saving conventions. You do not have that luxury in XP.
