When undocking the Program panel to put it on my second monitor, I'm no longer able to double-click and select objects in that view (to resize, move around, etc). Re-docking the panel doesn't fix it, resetting the workspace also doesn't fix it. The only thing that brings back the ability to select anything in the Program panel is closing and reopening Premiere.
On Mac OS Sonoma 14.4.1 with Premiere Pro 24.3.0 Build 59.
