[turba] Blank search not returning any entries -- differs by browser?

[David A Golden]

My apologies if this is a known issue.  I've searched the FAQ, Bugzilla, 
and did some general google searching, plus mailing list archives, so now 
I'm just going to ask and hope for the best.

I've got horde 2.0, imp 3.0, and turba 1.0 installed (via RPM) on a Redhat 
system.  It's reasonably up to date (e.g. PHP).

The problem I've encountered relates to a user that doesn't see any results 
from doing an empty search on the address book.  However, when I log in 
with the user's name and password and do an empty search, I do see several 
entries.  Off the top of my head, the only difference is that I'm using IE6 
and the user is using IE5 (or 5.5, I'm not sure).  Otherwise, Imp seems to 
work OK for him, so javascript is on, etc.

Any ideas?  I'm only a very part-time hobby admin, so I not entirely sure 
where to start with a detailed diagnosis.  (Telling the user to upgrade is 
an option, but I'd rather figure out the problem than just work around it.)

Thanks in advance for any help,

David
