Hi, guys. Thanks for the replies.
Yes, I'm totally sure I only have the desired clip selected when doing the edit(s). I've even done the Select None command before trying, just to be sure.
No linked clips, no groove clips, no grouping of any kind, just your run-of-the-mill straight audio recordings. Most recently, I've noticed the odd behavior happening within take lanes, although I'm pretty sure it's happened in parent tracks as well in the past.
Bouncing to clips may work, but I do a LOT of splitting and slip-cropping edits, so that could add up to take a lot more time/work...
