This often happens out of the blue, but sometimes when I have a PDF open in Acrobat Pro 8 and I click on the envelope icon to send the PDF as an attachment nothing happens. I end up closing and saving the e-mail message and sending it directly from Outlook. It seems to happen most whenever I type a long message. Then there are other times when I can click 'send' from Acrobat Pro and have the message go out normally with the PDF attached. Any idea why this happens?
