MSTS Activity Editor Crash Options

[ssstump]

After fighting with AE for hours because it crashed every time I used the zoom function, I finally fixed that by changing diasplay to 16 bit color depth.

Then I fought for an hour with 'invisible' consists. Finaly fixed that.

So, being over all that frustration, I worked for a few hours creating an activity. I then selected 'compute and save' and boom - Crash.

Happens every time I try, with the scenario I created, with other scenarios I load, on different routes, with default stock, etc, etc.

MSTS dumps a DXDiag file as if it is some type of video problem, but the contents are not helpful to me.

- Direct X is 9.0C (years more recent than MSTS). Running DXdiag shows no problems with video functions.

Re-installed MSTS and the updates - same

Installed MSTS on laptop - completely diff processor, video card, drivers, etc. - same

Searched the web for answers and found nothing that works.

Ran MSTS Trouble Shooter - (it's useless)

Anyone have any ideas (or a spare hatchet?) :-)

Thanks
