PDF Accidentally Saving As MHT

Hi everyone,

I ran into an interesting problem recently on a WebCT site. Using
Jaws, but I don't think that played a role. This was something that a
student showed me very quickly, & I haven't had the chance to do more testing.

The behavior was this: IE7 wanted to save an in-browser pdf as a .mht
file. Re-opening the .mht in IE produced garbage (I didn't think at
the time to change the file extension back to pdf to see what would happen).

I'm wondering what triggered the .mht saveAs. Perhaps the cursor was
outside the displayed file's window. There was a "Back to Parent
Document" button, so I'm suspecting the course author (or the WebCT
system) created a wrapper for the PDF. Or is this related to how IE
displays some PDF's?

Has anyone encountered this saving-as-MHT phenomenon anywhere, but
esp. in a courseware environment?

Thanks for any leads,
