#1 Dragging exponents can cause them to disappear

[Anonymous]

This program is great! Thanks to its creator(s).

There is one oddity about the handling of exponents. If I enter this new equation:

X^N = Y

... and then I drag the "N" to the right side of the equation, it simply disappears. I end up with just X = Y. It does appear to handle the dragging of the exponent if I use a number rather than a variable, for example:

X^15 = Y

... although it handles it in a way I don't expect and don't understand.
