Is this a new problem (where it says that the igo process ended) after exiting iGo - or has it always done this? I've seen Android apps do this before when exiting. It really is crashing - it's just not exiting properly for some reason.

If this is a new problem, then you might want to try clearing the application cache from within Settings->Applications - just to see if that helps. You can also try clearing the application data as well if clearing the cache doesn't work, but that will erase all application settings. This is just a generic troubleshoot approach for Android apps in general - not sure if it will fix your problem or not.
