When MDT Guide tries to display the minimized window, the map route lines get drawn all over the place, the UI freezes, and I get the following error from MDT:

Report the error to the MDT Guide AddOn. It is not affiliated with MDT

Ok, I will, but it's looks like the PullOutlines in the MDT API that actually crashed according to the stack trace, thought you'd like to know.
