Croquet crashing intermittently under WinXP

> Hi,
>
> I have intermittent crashing of the VM under WinXP. Honestly, do not know
> the cause as sometimes croquet works fine for the amount of time I am in it.
> The crash log entries all look the same, such as below. I have updated the
> latest NVidia drivers and still crashes, so I don't believe it is an OpenGL
> thing. No entries are made in the WinXP Event Log, so it is only internal to
> the Croquet app. Any help or pointers are appreciated.

> Crashing can occur right when I launch a Demo Master in Croquet, or after I
> have entered a world and am hopping around it. Reboots do not seem to fix
> the problem, though oddly the worlds will load fine once in a while...
>
> This box is very solid otherwise and is stable and able to run apps such as
> Second Life, Entropia Universe, ActiveWorlds, Qavimator, DazStudio, and all
> the regular 2d stuff.
