Text Box dilemna

[Stewart Lynch]

I need to find a way to trap and stop anyone from deleting selected text.
For example, in a text field, if one selects text and hits any key
(including delete, return, fwd delete or enter),  I need the the keypress
to be ignored and the selection disappear.
IE, I only want people to be able to hit the backspace (delete) key and
delete one character at a time and only if there is no text selected at
the time of pressing the key.  I need to stop it before it happens, or if
it does happen, undo it immediately without user intervention.

Any suggestions?
