Hi Michael,

Active AV disabled, MoI v3 reinstalled. With or without AV active MoI continues to crash as before.

I've been keeping Windows Task Manager open in the corner while I work - available physical memory with nothing else open is 1.65 GB and remains quite stable.

Where I said I'd managed to get the latest driver installed, I'm not convinced it was a complete install. The video driver configuration program reported a version mismatch. I'll have to do some more searching on installing the Nvidia drivers - it appears to be a known problem with no hard solution.

If you have any more ideas, I appreciate your time, but solving this is not urgent; I'm just saving more regularly and using v2 where I don't need v3 features.

Thanks,
Hamish
