Text entry problem – Wolfram Multivariable Calculus Course Assistant Review

When you try to insert the cursor in the middle of an equation and hit the backspace key, it just jumps back to the far-right end of the formula. In other words, if I want to edit a formula, I have to clear it and type it all over again. This is a big problem! I wish I could get my money back.
