corrupt windowProc()

hi,

i have a question:
i've worked with a corrupt windowProc() for a long time.
instead of calling DefWndProc(), i issued a
'return 0;'.
the problem is that, it messed with XP, and
when i (for instance ) move the mouse with
'control' pressed or 'shift',
the mouse jerks.
reinstalling the mouse and keyb. drivers doesn't
help.
how do i fix this?
(i already fixed wndProc().)

greets,

marc

I'm highly skeptical that a faulty window procedure could "mess with" XP if
to "mess with" means to cause permanent damage.

Rather, I'd attribute the jerkiness to the fact that with the key held down
you are generating lots of WM_KEYDOWN messages. You might want to check the
handler for the message to see what it is doing.

Regards,
Will

ok Will,

i agree.
but the problem is that it occurs 'outside' my own project.
for instance in 'outlook' (control/shift+mouse operations).
i can't 'take a look' inside the source code of outlook,
to see what it's WM_KEYDOWN is doing.
so, what then?

regards,

m

The most probable cause is that you have inappropriate
driver or some rude software on your machine. Corrupting
window procedure in a process (or any other function) can't
influence OS in any way.
