Recently I've been having an issue with Mission Planner 1.2.80 and now with 1.281. Whenever I try to connect via USB or radio to the APM a dialogue box pops up that steals focus. The problem is that it's a large vertical transparent box over the middle of the screen. Because it's transparent I can't see what the error is or where the OK and Cancel buttons are, assuming they are there somewhere. Since this box has focus I can't do anything other than to kill the process and program.
I'm running Mission Planner on Windows 7 on a Mac notebook using Parallel desktop VM.
I've attached a screen shot for reference.
