[GD-Windows] Win98 lockup problem

[Daniel V. <vo...@ep...>]

I'm seeing a problem here where most though not all Win98/ME machines =
will
cause the system to lock up after trying to run another D3D app after =
Unreal
Tournament 2004 exits. The bug is on both ATI and NVIDIA and happens =
with
both DirectX 8.1 and 9.0b but doesn't happen with e.g. Unreal Tournament
2003. I tried running killhelp.exe (which no longer seems to be part of =
the
DirectX 9 SDK) without success - is it supposed to work on a machine =
with
DirectX 9.0b installed? What is interesting is that D3D apps will also =
crash
if I start the game with the OpenGL renderer but not if I pick the =
software
renderer. This means both the OpenGL and D3D renderer must do something =
that
leaves the machine in an unstable state though I can't figure out what.

Remotely stepping through the code the app terminates (without a trace =
and
without locking up) in Direct3DCreate8 on second run with the D3D =
renderer
and locks in ChangeDisplaySettings with the OpenGL one.

Anyone got any experience tracking down a problem like this? Luckily =
Win2k
was already around when I made the switch from Linux game development to
Windows so I'm not too familiar with all the idiosyncrasies of Win98 :)
