All Black border and window frame

My first thought to your issue is this.
Are you by chance letting EQ2Map updater over write your eq2_mainhud_map.xml file? If you are then I bet there is your problem.
There have been similar issues with other UI's due to this. I have mine set to ask me if I wish to over write the file and I always say no. This way I keep the map window the UI's author made and I seem to have no problems with regards to my map.
While I am not a UI author, I do hope this info helps. If not, hope some one else who does know something about the EQ2Map program can help you.

If I am right though, simply extract that file from your zip of your UI and put it into your UI directory and see what happens. It may solve your issues.
