Odd IDE Inspector Behaviour

Working with 2019r3.1 on macOS 10.14.6 with multiple tabs open.
If i change a property of a GUI control, eg toggle a button’s default flag, the inspector slowly cycles through all the open tabs and comes to rest on the last one. The tab does not change I just end up with the inspector of the last tab in my current tab.

Rather annoying behaviour, any workarounds to stop this?

Odd. I’m not seeing that. I’ve got feedback://showreport?report_id=57894, however, which is driving me bonkers. Your problem might be related to mine. Not fixed for 2020r1 which makes me really annoyed.

Appears to be linked to “external” windows, ones i have moved to be external / shared between projects
