[Gtk-sharp-list] Gtk# instability nightmares

[Aaron Oxford]

Hi everyone,

As you may remember I've been having a hell of a time porting my GUI 
to Gtk#. After a series of tests I ran with Brad from Medsphere, all 
I can basically say is that Gtk# is unstable on my system. The 
attached program crashes on my system within a few minutes of operation.

I'm running a dual core Athlon 3800 with a gig of RAM under Server2k3 
and .NET2.0. We've verified that  the Gtk#, OS or .NET versions don't 
matter, and certainly the amount of RAM shouldn't matter with this 
test. BTW my RAM has been thoroughly tested with Memtest86 (the DOS 
one) during this ordeal.

Really my question comes down to whether or not Gtk# is stable on 
other people's dual core AMD/Windows setups, and has anyone else 
observed crashes like those listed below or noticed that they go away 
when running inside a VMWare machine?

Thanks again,

Aaron.
