Lots of people are getting this. I get it every time nearly, the only time I didn't get it was when I far away from the strip, and no map icons were showing. I moved it in towards the strip, adminteleported on it, then reopened and I crashed.
I got Peter to checkup the memory address that was causing the crash, and it seems that it's a problem with the icons - the memory address handled when things are written onto the screen, like wanted stars, textdraws (I think), and, you can guess, map icons.
Maybe an idea would be to not draw them until the user has logged in, and then add a preference to their savefile to see if they want the icons on or off. So, any problems, you can turn them off.
I know I will, as they don't really help me at all anyway, as I know where everything is...
