Been having a problem recently. For some reason, whenever I right-click on a timeline (and not on a clip), the only option I get is to ripple delete the empty space (and sometimes that option is grayed out so right-clicking may as well do nothing). Maybe I'm just crazy and it's always been like this but I swear it used to bring up an edit menu type of thing. I can still right click on clips, and I guess I can just use the edit dropdown menu instead, but I miss the ease of right-clicking to do something like paste a copied clip.
Does anyone know how to fix this or is this just my life now.
I also just began having this problem. I could right click in any empty area in the track lanes on the timeline to add a marker at the playhead to the frame counter above, using a context menu that appeared. I would only be able to add the marker in that location if I did NOT have a track selected. Now the entire lane between two clips turns gray, and the only option I have is to ripple delete. All I did was leave the computer for an hour to eat dinner, and I returned to this behavior, though I must have done something to cause it.
The "correct" answer below is absolutely incorrect.
