[BUG] Multiselect crashes N++ #17126
Description
Is there an existing issue for this?
- I have searched the existing issues
Description of the Issue
In v8.8.6 and v8.8.7 (as of today, the current version), multi-selection can crash the current N++ window (other windows are unaffected). Downgrading to v8.8.5 helped, so this is a regression.
The crash is reliable. I always happens when I try it.
Steps To Reproduce
- Be on Windows 11.
- Install version v8.8.6 or v8.8.7
- Use Zenburn style (not mentioned in Debug Information)
- Open a file (e.g. the changelog file)
- Select a span of text (at least 1 character)
- Hold Ctrl while clicking on another part of text
Some details (like the style) might be overly specific.
Current Behavior
N++ exits without warning after 1 s.
Expected Behavior
N++ does multi-select like (or very similar to) v8.8.5
