I have poured over reports and preferences and can't find option for this behavior so don't know if it's intended or a bug. If it's intended it's still bad it can't be disabled.
Any time I do a commit anything I have on clipboard is wiped clean, the clipboard is literally zeroed out on macOS Big Sur 11.4 and sourcetree 4.1.2. I can reproduce it 100% of time. I simply copy anything to clipboard, commit to a git repo, clipboard now blank
this behavior didn't happen on sourcetree 3.x it is new to 4.x It seriously slows down my work flow which sometimes involves copy and pasting commit message into up to 12 repos and now I have to add an extra step of recopying the text from a text document first sincce it's wiped for each and every commit.
Thanks, can also confirm it's fixed!
