MINIGUI sometimes gets stuck on low score

When I start the program in minigui mode sometimes it jumps to a score like 26 or 30 and then seems to stop. I do this and then maybe 12 hours later it is still on the same low score. Surely it can't be stuck on just working out low scoring placements for 12 hours?

I have noticed this on my home and work PCs, even when nothing else is running.

It doesn't happen all the time.

Usually I close the program if the score didn't go up within about 60 seconds, and restart the program in minigui mode, otherwise i think the program seems to get stuck on a low score.

Has anyone else noticed this?
