[ic] Unusual IC search issue

[doug1 at ultimatepassage.com]

Happy New Year all,

I recently setup an advanced search function for one of my clients.  The 
search works flawlessly on opera, konqueror, mozilla, etc.  It does not 
work on internet explorer.  An identical search on IE generates a 
"Sorry, no matches for" message followed by the search string.  I looked 
at the session values they are identical except for the mv_numeric 
variable.  On IE the mv_numeric is being set to:
'mv_numeric' => '1 1 1 1 1 1' while on konqueror it is begin set to: 
'mv_numeric' => '0 0 0 0 0 0 1 1 1 1 0 1 1 0'.  The konqueror version is 
correct.  I have tried this version 5.3.2 and 5.2.  I would be grateful if 
someone could point me in the right direction.

Thanks,
Bruce

Here's the search:
