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

I think a trivial change to LR would fix the issue, without needing a reproducible recipe.

Currently, when you select a thumbnail and drag it towards the next photo and release the mouse button before the cursor reaches the border, LR will change the sort order to Custom, even though the order hasn't actually changed. See this screen recording. (Some pointing devices conspire with LR to cause these spurious drags.)

LR should only change to Custom if the order actually changes.

I have given step by step details of the actions I take (in LR & Ps) and the results, which I can repeat for you.  But I am not sure, from what you have said, that this will reproduce the issue on your computer.  Are there any system files or logs that you would find useful ?

I can confirm software and hardware, but this is not always specific, as for example the problem has occurred over many updates of macOS, and also several updates of Wacom drivers (and several updates of LR and Ps software). And to confirm I am currently using the latest versions of all.  I have also tested several levels of sensitivity settings for the Wacom stylus  

To me it all points to a conflict between LR and Wacom software/settings in some way, which is why I wondered if any logs would be of use to you ?

The chance depends upon getting a reproducible scenario documented that we can pass onto engineering. They can't fix it unless we can show them it is broken. To that end we need specific system information and a step-by-step process for reproducing the behavior reliably. 

As a Lightroom Classic user with 380K images cataloged, I've sent at minimum 6500 images (and probably many more) from Lightroom to Photoshop over the past 13 years.  I recall it happening 1 time about 7 years ago. It hasn't happened to me since.  What does that mean? 

• I have a workflow that is slightly different and don't encounter it?
• I have a system configuration that doesn't reproduce the scenario?
• I have a higher tolerance for this so it ceases to impinge upon my awareness? 
• All of the above in some combination?

If anyone can give me step-by-step clean steps for reproduction, and I can reproduce the behavior, a bug will be written immediately and then I can escalate it through the channels and the Product manager.  Till that time, I continue to gather data and investigate possibilities. 

In three years, this post has only garnered 6 Me Too votes. It wouldn't hurt to hit the button at the top if you haven't already. 

Is there any chance of this Rikk ?

no...no wacom software.

I also use mouse only.  However I think I've managed to limit where its happening to filtering while in the develop module.  If I filter in Library, then go into develop to work on the higher rated photos and then back out, the order doesn't change.

John, I will rephrase my question to you. Do you have a tablet attached or a Wacom driver installed - regardless of whether you use it or not? 

It happened to me sometimes before I got the tablet.  After I started using the tablet, it happens almost every time.  By saying almost, I mean 99% of the time.  I don't need to unplug the tablet.  I have a mouse also.  When I use the mouse, tablet still plugged in, the problem rarely happens, if at all. 

I agree with Nick, a simple lock to toggle on/off for the sort order would solve this issue.

Rikk...seriously? 100% of my actions in Lightroom is mouse related, the capture time order changes at an extremely annoying rate. 

I do not have a mouse, so have not disconnected my tablet.  But I understand this issue occurs for others who do not use a tablet.  Is there any way that a viewing choice can be locked i.e. on 'capture time' ?  I literally never use any other sort order !

I could try a test without the Wacom, but not very easily, and probably only confirm what others have found and struggled with as well
