Gary, Frank,

I have installed a system on another PC and run Qt3-designer (under new
XPhoton or under XFree86 4.2 without photon) WITHOUT hang. up It works better
under XFree than under XPhoton (always keystroke problem).

I have re-installed from zero a system on my development machine. This
machine hang without Qt3 or XFree4.2. Just after installing I start network
configuration and it's hang up.

So I think it's not Qt3 or XFree4.2 but a problem with my system ! What ?
infortunately, I don't known :-(

I used this machine for 4 months to developed a little PhAB application and
I've never had such problem.
A precision, it's a PICMG motherboard with two PIII. I have build my /.boot
with /boot/build/qnxbasesmp.build.
I think I will search and talk about that on qdn.public.qnxrtp and perhaps
recontact you later. (Or, perhaps you have a great solution :-).

Thanks for your help.
