Success! Thanks Charles!
If anyone wants to know I had to change ubb_forum_summary.cgi:<pre>} elsif(($vars_pntf{Docked} eq "no") && ($vars_pntf{TopBottom} eq "top")) {
$pntf_locations[0] = qq(<?PHP pntfGetCacheForSummary('$in{category}', "$TBT_escaped", "$TBB_escaped$vars_config{'jc'}->{'no-br'}", "%%COLSPANS%%") ?>);
</pre>
to<pre>} elsif(($vars_pntf{Docked} eq "no") && ($vars_pntf{TopBottom} eq "top")) {
$pntf_locations[0] = qq(<?PHP pntfGetCacheForSummary('$in{category}', "$TBT_escaped", "$TBB_escaped$vars_config{'jc'}->{'br'}", "%%COLSPANS%%") ?>);
</pre>
In a nutshell, changing "no-br" to "br".
This assumes you're using a Standard template. I checked the vars in ubb_lib like you said and sure enough...<pre> # Standard template set vars
$vars_config{'jc'}->{'is'} = 0; # 1
$vars_config{'jc'}->{'no-br'} = '<br />'; # ''
$vars_config{'jc'}->{'br'} = ''; # '<br />'</pre>Just the opposite of what I'd expect, but once I knew what I was looking for, it was an easy fix.
Woohoo!
