Hi:
This problem started for me in Dec. 2013 after Google did an update.
I use Cox's Enhanced Email with the Google Chrome Web Browser.
When I try to reply to an email message, I cannot backup using the Back Space key.
In order to correct an error / typo, I must Hi-Lite and Delete the error, then retype the correct text.
Currently, I do not have this problem when using Firefox or IE8 ... but ...
about a year ago, I did have had this problem when using IE8.
How can this be fixed ?
Thank you
