Well, I'm still at it. I took Kelvin's advice and updated drivers,
windows, DirectX 8.0a, running in Emulation mode using -Dj3d.d3ddevice
flag, but I am still having the same problem: my applet/application
hangs Windows 98.
I have found that my applet sometimes freezes while running, but
sometimes it even hangs before the first frame.
Lastly, I tried using Java 1.3.1-beta. For the first hour, even my test
program (attached) would cause the machine to hang. Of course after
investigating for a couple hours, it doesn't hang anymore. :-? Nope,
no stack trace dump.
I need serious help. My full-up app uses Java3D and Swing, but my test
app does not, so it's not a Swing thing. The only thing I can figure is
application size. Does anyone have a "large" app I can try on my
Win98/ME machines?
