I'm using Outlook 2003 in an SBS 2003/exchange environment on Win XP Pro

Alt+S suddenly stopped working! I don't know how or why - but now instead
of immediately sending the email, it acts like I only hit Alt, and
highlights the send button. I can hit enter and it then sends, but WHY??

Just to be thorough, I checked other computer on the network and it's only
mine of course.

Thanks for any suggestions you can offer!
