I’m running Beta 9 and found a few gremlins.
The > arrow does not always appear for the event running in the sequencer window. It is simply absent.
The 2nd is an exception error. I have low stretch as default on acquisition. When I right clicked and chose no stretch, I had an exception error. Pressing continue - no problem, but at any time in the future, trying to choose no stretch again on that image caused the same exception error.
If I cycled through the images with the green arrows and tried again, no issue at all in removing the stretch.
