I have a two-monitor setup on my Mac. When I right-click in a pane that's on the second monitor (Project pane for example) the context pop up menu appears in the left monitor (in the Source pane for example) instead of where I clicked.
The left monitor pop-ups appear as expected in the pane where I've right-clicked.
This only happens when I right-click in panes that are on the right monitor.
This doesn't happen in PProCC2015.1.
I've rebooted, trashed the preference file "com.Adobe.Premiere Pro.10.0.plist" in the Users/[user]/Library/Preferences folder, started a new blank project. Still same weird behavior.
