The FIRST time I try this (I’m already 3 levels deep in the outline, btw), the TOP document of the selected 4 moves right. The others stay in place. What? However, I can Ctrl-Leftarrow to move it back.
The SECOND time I try this (immediately afterwards) all 4 docs move right, and Ctrl-leftarrow will move them back.
Inconsistent behavior indicates some bug is present.
And I think the strange behavior only happens if Scrivener is recently loaded and this is the first time this function has been called. Not sure. I’ll check this again later, once time passes without Scrivener loaded, because I can’t reproduce it right now.
To throw another variable at you, what view mode are you in when you see these oddities? We currently have a bug that affects binder selection while in Scrivenings mode, could that be what is causing the effects you are encountering?
