Surveyor keeps minimizing on its own ??

[Winnipeg]

I have been spending endless hours on a specific route on surveyor and just the other day all of a sudden every 30 seconds or so it minimizes itself to the desktop ?
Its no big deal to bring it back, just click on the taskbar tab, however its becoming very annoying to deal with.
Has this happened to anyone else ?
And does anyone have a solution for this ?

Take care.

You must have another program running in the background.

I find this when messager ( Yahoo/MMS) kicks in if someone tries to contact you, thats why I stop them before starting Trainz

I shut down everything running in the background, including my firewall & anti virus programs and te darn thing still minimizes alot.
I double checked my drivers for my Niviia, that's all up to date.
I'm convinced I got some corrupt content on my map somewhere and its caushing it to crash. Its gotta be.
