Memory management

[rickk]

Thanks for that. I'm guessing that a restart would be necessary for the change in settings to take effect. So at that point I would have already had to save my work, and re-start before continuing, which serves to clear the undo memory anyway.

I was just hoping for an easter egg, I guess, thinking there might be a way to delete undo steps similar to deleting layers in the layer dialog....my bad. ahh well.......
