I believe I have a similar problem when it comes to hovering/selectng from the top menu items in InDesign when using the Adobe CC 2017 version. For instance, when I hover on LAYOUT, it shows the corresponding drop down menu. THen when I move my mouse over to TYPE, it shows the drop down menu for OBJECT, unless I go back to LAYOUT where it then shows the drop down menu for TYPE.
In other words, it is displaying very erratic behaviour. Selection becomes a nightmare and very time consuming to pin down the preferred selection.
Is there a way to reboot InDesign so it behaves normally?
