Send Button Does Nothing Using IE10

Hi:

I am using Windows 8 and IE10 and everything seems to be working fine, except when I hit the send button, nothing happens. So, I can create, reply, but not send an e-mail.

The send button works just fine with Windows XP and IE8, or Windows Vista/W7 and IE9.

I also tried the IE10 release preview on my Windows 7 PC, and the send button won't do anything on that platform either.

Does anyone have any idea why this is happening?

Thanks.

Paul
