Error R6025 - pure virtual function call on SWS/BR: Toggle preview take under mouse
I get the error in the title and Reaper crashes when I use SWS/BR: Toggle preview take under mouse through track, and switch to a different project tab while the preview is in progress. 100% repro rate.
I can confirm the crash here.
But since it's a bug / crash related to an SWS action it should rather go in the SWS issues tracker, not the Reaper bug forum.
