Have you installed any Mail add-ons? Check in: ~/Library/Mail/Bundles /Library/Mail/Bundles Also, you may want to see if you have any input managers that could be causing problems: ~/Library/InputManagers/ /Library/InputManagers/ Also, check under System Preferences/Universal Access/Keyboard and make sure sticky keys is turned off as this may explain this somewhat bizarre behavior. One other option is to try a safe boot or other troubleshooting techniques listed at apple's website: http://www.apple.com/support/mac101/help/ Give that a try. I've not had any similar problems with my 10.4.5 update and have a number of Mail Bundles installed (GPGMail, MailTags, etc.) Good luck, Norm --- Norman A.
