Full Text display problem in MySQL Text column

Question

I'm having problems with CF MX 6.1 displaying any output from
a database when I exceed about 4,500 characters in a MySQL database
column.
I'm not doing any funky joins, just a URL variable to select
the row. I have a "bio" field and when that field exceeds more than
4500 characters, CF returns nothing from that row at all.
(including other columns).
The version of MySQL is 4.0.17, CF is MX 6.1. The same error
occures in both the CMS I built using InterAKT's DW extensions
(Nextensio and KTML) and in my basic detail page.
Any idea's why this is happening? Thanks for the help.
btw, the site is www.goodstuffpr.com - the client's pages are
the main culprit, although I've been able to duplicate the problem
in the news section and press releases as well.
And the CF code:
<cfparam name="URL.col_id" default="1">
<cfquery name="rsClients"
datasource="goodstu_database">
SELECT *
FROM tbl_clients
WHERE col_id =
<cfqueryparam value="#URL.col_id#"
cfsqltype="cf_sql_numeric">
</cfquery>
nothing special. the output is:
<h1><cfoutput>#rsClients.col_name#</cfoutput></h1>
<p><img
src="../uploads/images/<cfoutput>#rsClients.col_image#</cfoutput>"
alt="" class="floatLeft"
/><cfoutput>#ParagraphFormat(rsClients.col_introText)#</cfoutput></p>
<h2>Biography</h2>
<cfoutput>#rsClients.col_bio#</cfoutput>

What does it show in your ColdFusion Administrator DSN
advanced settings for BLOB, CLOB, Long Text Buffer (chr), and Blob
Buffer(bytes)?
