--- Comment #5 from Stuart Middleton Stuart@houseofanime.org 2011-07-01 09:14:52 CDT --- Restested in version 1.3.23 with no change in behaviour.
Tried overriding shlwapi with XP version and that produced improved results (a separate problem with the application caused clicking on a link to crash the application, but it appeared to doing something when I clicked on the link (which caused the crash) and the scroll bars were working).
