I'm having a peculiar problem with one workstation. (GW 8.02)

When anyone at this workstation goes to the "properties" on a Sent Item,
instead of opening the properties page it attempts to open a GW_00012.tmp
(or similar number) using Internet Explorer. (This isn't a problem for the
same user at another workstation.)

I found the same problem on a google search . . . the resolution was to
re-associate the adv_prop.xsl file with groupwise. I've done this, browsing
to the grpwise.exe file (couldn't think of another file) but it still doesn't
work. I've uninstalled and reinstalled the GroupWise Client and ran
a Registry Cleaner but the Association persists. [No other copy of the
file are located on the C: drive and I even deleted an Internet Link for
opening the file, but still no good.]

At this point I've run out of ideas on how to get this back.

Any advise would be appreciated!
