Greetings, Frost!

Thank you very much for your patience with waiting for a response to this problem that you have encountered. Unfortunately, according to our records, it seems that the development team was unable to reproduce the problem. In their test, they were able to properly reply to the last person who sent a tell by using pressing Ctrl+R. In order to make sure, they tested it on Windows XP, Windows Vista, and Windows 7. Thanks again for your patience and for your report!
