On all Pc's through several years of Proseries this action does not seem to work or be responsive.

It should go without saying why this is interruptive and time consuming but since it is not addressed maybe it should be explained.

When a name or a social is given and an accidental selection is made and replaced an undo feature would save an individual from having to re-key the information and in many cases would avoid them having to look for the information that was replaced.

Practical Solution: Make sure that simple function works on the software.

Current Solution: Close the return completely, do not save and hope that you saved before the error so you don't lose too much.
