So, I tried to open the timeline window, and when I selected the highlight of the menu stayed after closing the menu. This has happen me before with other softwares, like residual data or something, that floats around until you reboot the software or the computer, in case of Windows. But this little thing does not go away!.
This has a fix or something?
