24.0.2.0: Crash on select line and drag up, macOS

[tuchman]

Problem can be relatively easily reproduced.
1) Cursor in middle of variable "current_offset" in line 4 of attached file
2) Then, in VERY fast succession...
2.1) Select line 4 by triple-clicking on track pad, and
2.2) Click trackpad and drag line 4 up towards blank line 3
3) SE crashes...

Thanks, that was a very good bug report.  I was able to reproduce the problem and am working on a fix for the Qt libraries to put into the next release.

Are there any updates or patches to this problem? My  SlickEdit Pro 2017 (v22.0.2.1) for Mac crashes any time I try to drag highlighted block of code.

You would need to upgrade to SlickEdit 2020.

As a work around, you can disable "Allow drag drop of text" Tools>Options>Editing>General. That way, you can't even try to drag/drop text.
