JabRef version

Other (please describe below)
6.0-alpha.403

Operating system

GNU / Linux

Details on version and operating system

ubuntu:22.04

Checked with the latest development build (copy version output from About dialog)

• I made a backup of my libraries before testing the latest development version.
• I have tested the latest development version and the problem persists

Steps to reproduce the behaviour

1. Launch JabRef.
2. Create a new library and add an entry; open the entry editor.
3. Open the Source tab and make the Bib(La)TeX invalid (e.g., delete the final closing brace }).
4. Switch to another tab to trigger the error handling dialog.
5. Click the dialog’s OK button to close it.

Expected Behavior

• Clicking OK should close the modal dialog and return control to the entry editor so the user can continue editing or fixing the source.

Actual Behavior

• The “SourceTab error” dialog is immediately shown after clicking OK.
• The dialog continues to block the entry editor view, preventing interaction.
