Just had first glitch where Helicon on Windows hung during an undo operation while retouching. It was using a fair bit of ram (about 17GB) having loaded and processed a few raw stacks for comparison purposes, but there was more available. When it hung there was no CPU activity so I had to kill the task. There had only been a couple of retouch operations.
Is there any kind of auto recovery? Would have been nice to have been able to get back to the same state in terms of processed stacks on relaunch.
