Are you sure you are using superscript? I get that symbol if I use the
script *font* and try to type a minus. How are you getting the superscript?
This problem occurs when the character you put the superscript on is a
special type. For example, I often use \mathbb{R}^n and terms like it.
In LyX, if you type \mathbb and hit space, or use the menu selection,
you are put in that blackboard bold mode. If you don't hit another
space after the R to get out of that mode --- there are red corners
indicating the special mode on-screen --- then you actually are entering
\mathbb{R^n}, and TeX gets very confused about what that n is. With the
tap on the spacebar, the red corners disappear and all works as it
should. The same holds for scripted characters like \mathcal{A} and
similar things.
