Another bug I have, and this has been happening in many versions of PP for me over years, is that the work area handle can't be grabbed to be dragged! It only relocates the timeline's play blue line... Well, at one point it finally works, but very often it doesn't. Sometimes I manage to grab it by clicking on CRTL at the same time, but it's still not always happening, so it might just be working randomly... I googled it up, and it seems it has occurred to only one user over the years and with no good solution.
Any chance someone would know how to arrange this?
