new problem with mime viewer - one machine only

[PureMoxie]

Within the past week or so, something happened on my laptop that causes a problem with stored .eml messages not being displayed in the MIME viewer - if they are HTML messages.

When I browse to the .eml item in UR, IE is displayed in the background with "page not found" and the IE download dialog pops up ("do you want to open or save this file?").

This only happens on my laptop; the same items display fine in UR on my desktop.

Any ideas on how I can fix this?
