On occasion, SGP will crash (maybe once/twice! a night and it’s a major issue because I have to shut down all the other programs and then reboot the computer and restart everything. It would be much better to leave everything running and just re-run SGP. But without a clean reboot of the PC - I get this error. FORCING a full shut down and restart which waste a lot of time. What causes this? Can anyone else run a crashed to OS SGP again without rebooting the machine?
