The attached image shows the cursor to the left of the period while the true location is at the end of the line. So if I were to press the delete key, it wouldn't delete the period but instead move the next line up to the end of the current line. The cursor can be 1 or 2 positions offset and it might have been to 3 before. This makes it more difficult to edit since it's not consistent and you can't account for it.

I have seen this happen with weird fonts. I don’t remember which ones, but changing the font made the problem go away for me. Your suggestion of using a fixed width font was a good one.
