Yes, this was a test, just a small JPG file I sent to my BB which I have always been able to open. I just tried it agian and this is what I got:

Blue line under the address fields, on the next line is says [1 Attachment] and at the very bottom of the e-mail there is a blue line and below that it says application: winmail.dat (33K)

Update - It has to be something in my mail program (Outlook) because I did the same test using my g-mail account from the web and was able to open the attachments with no problem.
