I mentioned it to technical support more than a year ago, but the function: showing the overlays over the mouse does not work yet, no more in C10.5 than in C11. Only The Always and Never Works Options
Which window/area do you refer to, please?
In the project window, the overlapping events. Show preferences: show, don’t show, show on mouseover. It is the latter that does not work.
p.s. (sorry for the specific terms, I work in French)
OK, I see, now I know, what you mean.
This is known and already reported issue. Thank you.
