Oops. Sorry. I guess I meant. Shift-Enter.
(leaving the the Full path to the TIF in the original Explorer window.)

Ah. I should also have said switch back to the TIF viewer
or close the current window I guess...

See? I was still assuming you were looking at the TIF viewer...

Not for me. Did you capture it from the Address bar of the TIF viewer
or from the Address bar of the Red-X window?

I do this paste a lot and probably overlook some of the switching details.
(It's really a lot easier to perform than to describe. ;} )

Great! That shows that the local file association is working but the
web file association is not for some reason. Possibly MIME related?
You could try disabling MIME sniffing (in Security Settings, Custom Level...
Miscellaneous section)
Disable: Open files based on content, not file extension

Note: I think that this may be one of the many undocumented (requires restart)
options. I would wait until all IE windows are closed (iexplore.exe not
an active process) before trying to test this change.

Note this is not a permanent change I am suggesting, just a temporary
one for a test.

BTW I wasn't aware of imgutil.dll. Looks like it would be involved with
the MIME sniffing at least. I suppose I could test both cases with
RegMon and FileMon some time. Or perhaps Ramesh will clarify
for us.

That's the one I meant. It had evidently taken over the local file association
so I was imagining that it might have affected the web file association too.
(Purely speculative and just something else that I would try, to test the scope
of the symptom.)


Good luck
