P: Custom Order lost with slight accidental movement of thumbnail in filmstrip

Here's another example at 5:00 mins

So 20 seconds into the video you can see the order change on its own, I didn't even click on the image, just hovered the mouse over an image.

I didn't even notice it had changed til later, as you can see in the video.

I found that it changes from Capture to Custom on clicking an image, got it on video. I just need to edit the useless section of the video. Will post shortly.

To confirm - I work in folders, not collections (importing from folders as set up in Finder, working on the photos contained within, and then archiving afterwards from Lightroom to avoid overloading)

Ok definitely the sort is changing without editing, all 2009 folders were at Capture. I reset LR and the folder I last used is now at Custom without doing anything. It's a bit random to try and capture on video but will try tomorrow.

Well spotted John...so it is, something is changing it, re my last post.

Actually I found something odd.....you dont actually have to send an image to PS for editing, LR seems to change from capture to custom without it. I set all my folders in 2009 to Capture....went back to double check and one has set itself to custom without editing anything.
I will see if I can video it.

The video shows Sort: Custom Order before you invoke Edit In. So at least in this case, it's the stacking issue causing the reordering.  A video showing Sort: Capture Time before you invoke Edit In could be helpful, as would starting in Library grid view rather than Loupe view -- that will show more LR settings that are hidden by Loupe view.

The point is.....something is causing the sort to change, I always set it to Capture
