I broke out my Programming Python (2nd Edition) book and doubled my Tk knowledge in the space of an hour or two. I went through the tkui and fixed up a lot of issues involving thread contention. The tkui should be more stable now, titlebar manipulation works again (through the settitle(...) method), NamedWindows work, I fixed the Autotyper, and I went through and cleaned up the code while I was at it. All in a good night's work.
This was the last big issue I needed to solve before releasing 3.1 which has some sweeping fixes in it.
