There is a minor bug with the right click context window and duel monitors.
I have 2 screens, one is located above the other. When I am using Jedit and right click to open the context menu it will, the first time only, generally be located where I opened the menu.
The issue is any time after that, the context menu will be displayed on the above monitor and not the bottom one where the Jedit application is open at. This will happen in both full screen and window mode.
