If you have a look at the tour on the following link, you will notice that in the lower right map menu, the word "Lower" has no "r" on the end.
When I put this together in the editing mode, there does not appear to be a problem but when I publish, the "r" disappears. If i change it to another letter such as an "n", there is no problem except for the fact that "Upper is not spelled with an "n". I have tried playing with the dimensions of the text box but this does not help. Some other font types seem to work and if I add a second "r", they both appear, giving me "Lowerr". It seems to be some kind of glitch in the output generation and it is driving me nutty.
