attachments received are jibberish

I am using mail.app to access my Groupwise account (IMAP) and my students are required to send me many attachments. Lately (since upgrading to 10.4), I am getting MS Word files and .JPGs and about 1/4 of these attachments show up as jibberish and not as attachments. If i start up Entourage and get my mail, I can clearly see the attachments and download them just fine even though they don't appear in mail.app.

I upgraded my wife to 10.4 just yesterday and now she is experiencing the same thing with MS Word files from her students.

Here's an example of just a small portion of what appears in my email text instead of the attachment i should have received:
