Are you by any chance creating windows in different threads? What style you
David, yes the machines have different graphic cards (I tested on
desktops
and notebooks). And our clients are in Italy (using Italy Windows
systems).
Since we haven't changed anything in our tool for a few years (we are just
maintaining it now) and the only thing changed is the XP SP2 (and on Vista
it's OK again; I didn't change anything else), I suspect there's sth
special
in SP2.
About the application: in trying to find out why, we have created a
simplest
program with one window that contains a "notebook" (same as VC++'s
PropertySheet), and in the pages of the notebook, there're many StaticText
controls, and many other controls, there're no code to do any processing,
just this GUI stuff (window + notebook) to test the refreshing speed.
Does VC++ call this CreateWindowEx() to create the static text controls?
(I
checked the source code of the C++ SDK (NOT VC++) we use, it calls this
API
to create static text control and some other controls like buttons,
listbox,
etc) Also, is there another call to do the same job?
I'll try using VC++ to call this API and see what'll happen.
Thx for your help!

Have they got different graphics cards in them?
I did try using VC++ V6.0 and created a PropertySheet and a few pages
and
created many text strings in the pages. It works fine, no problem at
all.
That would seem to point the finger back to something you're doing in
your application. Have you tried removing as much code as you can from
this window and seeing if you can pin it down?
