I am stumped. I have a customer using Outlook 2003 (with latest updates) on a Windows XP (w/SP3) Pro machine. When they right-click a file and select "send to - mail recipient", everything functions normally. A message window pops up with the file they right-clicked attached and a brief message automatically inserted in the body of the e-mail. However, when they add any valid e-mail address and click send, nothing happens. When they hover the mouse over the send button, it highlights like it should, and when they click it, it depresses like it should, but nothing happens. The window stays open, and the message never gets sent. Sending a message inside Outlook by clicking "new" works fine, even with an attachment. This only happens when they use the "send to - mail recipient" option. They would send attachments the other way, but the "send to - mail recipient" option lets Windows resize their pictures for them automatically and they want to use that function.
Any help would be appreciated.
