I clicked somewhere on my map after trying to pan down. I think probably the map hadn't finished refreshing and this error popped up at random from mscorlib.
Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
I have a try catch around all of my code to catch any errors my code might throw (an effort to try to help figure out these errors) and it wasn't reached, the software just bombs.
(I should mention that I'm in SingleThreaded mode.)
