Weird... I waited a few minutes and now the "overlay" panel is normal again. So maybe it just needed me to turn off the program and come back in an wait a moment.

Hi there,I think there maybe something buggy with the Window> Overlays Panel in InDesign CC 2015.I had my last update about 29 days ago and it seemed to look OK before that.However now if you try to select one other the items like video or audio the text and fields in the panel "overlays" themselves...
