I can pretty consistently get a crash if i zoom in on the map. It seem to happen when the map goes form icons to the detailed images. I have been playing always zoomed out to avoid this (which looses a lot of the pizazz of the game). Problem has been and is still there in 6.1.1
I submitted ticket/dumps in the past and was told it was a memory problem. Drivers are UTD, 8G ram 8G swap file (tried bigger-no help)
Q: would you like more dumps? Really want to be able to zoom in
