RC2 - Ran fine for me - Still bug in displaying X

RC2 ran great last night with my new RC12 first light evening. 6 different targets, meridian flips, autoguiding, centering all great. Could not test any autofocus with the RC12 since my focuser is not here yet.
Still have the bug where the red X for deleted images does not show up on a deleted image, but shows up one image before or after, depending on which direction you are moving through the images.
The correct images are being marked bad correctly. It’s just that the red X does not correlate with the correct images.

I have still never been able to reproduce this behavior. This leads me to believe it is a timing issue. I have devised a “fix” that I’m hoping cures this issue. Would appreciate feedback on the next release.

Thanks,
Ken
