With the update to RC16 I can’t change any document icons because the triangle to display the icon submenu is missing in both the main menu bar and the Binder right-click submenu. I haven’t seen this behaviour in any of the previous betas. See screenshot.
Did that already - it’s beta software after all.
Dug a bit further in. The problem is erratic. Some projects show it, others don’t (even when opened simultaneously).
Then a project that did show it, starts to not to - even within its same open session… Grrrr…
Have done a bit more testing. Your description is indeed a better characterisation of this bug’s behaviour. Thank you.
Hopefully it will be fixed in RC17. I use coloured notebook icons to help label WIP items for easier progress tracking. It’s a pain not being able to do this now.
