P: SDK: Modal dialogs don't always close properly

[johnrellis]

Dialog windows created by LrDialogs.presentModalDialog() don't always close fully on exit.

To reproduce on LR 14.2 / Mac OS 15.3.2 / Macbook Pro 16" 2023 Apple M2 Max:

1. Download and install this plugin:

https://www.dropbox.com/scl/fi/rpm9osljz9yv9arxu8yqk/dialog-bug.lrdevplugin.2025-03-24.zip?rlkey=fuv...

2. Do File > Plug-in Extras > _Dialog Bug > Bug and observe this dialog:

3. Click OK and observe the dialog close properly.

4. Do File > Plug-in Extras > _Dialog Bug > Bug again and observe the same dialog.

5. Click OK and observe that the dialog hasn't completely closed:

6. The dialog remains until you restart LR.

This bug persists after resetting preferences and opening a new catalog. I first noticed it with my Debugging Toolkit,  where it's a serious annoyance. Nine others have reported similar symptoms with creating snapshots starting with LR 14.1.1.

It happens for many of my plug-ins.

What is strange is that in certain cases I use a similar UI as you do but it doens't happen.

At step 6 I can dismiss the dialog by clicking the UI BUT it simply goes in background and is still there in the "Windows" menu.

Thanks for the report @johnrellis  - I've logged this.

The recipe still produces the misbehavior in LR 14.3.

From the team: 

"Not observing this with the attached plugin. I am on macOS 15.5,  could you please check if this is an intermittent issue?"

Today I tested with LR 14.3.1 / Mac OS 15.3.2 and still observed the bug (first observed with 14.2 / 15.3.2) with both the plugin recipe here and with New Snapshot.

Then I updated to Mac OS 15.5 and no longer observe the problem with LR 14.3.1.

Closing as we can no longer reproduce.
