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

The sort order is "Custom Order".

Check your sort order for the Folder/Collection in which you are located. It is likely set to Edited Time or similar. 

My issue is slightly different, but it might well be related to the original poster's problem. If I am in a folder with custom order, after the Photoshop editing the psd+raw file stack goes to the end of the filmstrip, which is also annoying. Is this reproducible to everyone involved?

Thanks,
Alex

Thanks Rikk!

I agree that the issue does not necessarily occur due to sending to / returning from Ps, and that it does appear to be down to the sensitivity of the slightest of movements in the filmstrip.  And that this is also irrespective of pointer tool being used (mouse or Wacom stylus pen).
On this basis a reduction in sensitivity, to actually fully moving an image beyond another image, or the application of a lock on the filmstrip sort order choice, would be a logical and much appreciated 
Thank you 

I will log an issue with the team. I have retitled the thread as Edit in Photoshop does not appear to be a contributing factor. 

Rikk,

"It sounds like you two are in agreement that this is not an Edit in Photoshop/return to Lightroom issue. Can we chalk this up to subtle unintended movements in the filmstrip? While Wacom may or may not be involved, its involvement is more likely to be the less precise nature of Wacom hover/drag when working with the filmstrip. 

John McNair & Nick Harrison - are you in agreement with this analysis?"

This^^^.  I agree with John and Nick.  It's not a Ps issue.  That's just where I noticed the change had occured.  But now I can look in Library after being in Develop and see the change of Sort order has happened before I've sent to Ps.  I have noticed when I tap an image with my pen, sometimes it moves slightly, enough to show the black line when an image is moved.  I don't actually move the image, it's just a slight movement because the pen-tablet interface is very sensitive.

You should be able to recreate this easily by slightly nudging and image but not actually moving it.  I can recreate with a mouse intentionally.

"Can we chalk this up to subtle unintended movements in the filmstrip?"

It does seem that this is a cause of what people are observing here.

Rikk,

The sort change happens a lot and I notice it more when an image returns to lightroom, but it could be that the sort change is done before the image goes to PS for editing. I am thinking that locking down the filmstrip is probably a good start then take it from there.

Rikk,

I don't ever recall the sort order changing when returning from Photoshop but I have had the sort order change several time because of moving the photos slightly in the filmstrip.  This happens accidentally and more often when I select photos and start to move them to a collection and change my mind and want to select different photos.  I start the drag, drag back to their original location, let go of the mouse and the sort changes.  As John said, the sort shouldn't change unless you actually move the photos in the filmstrip.
