post us the section [file] from your template
Make a try by moving %comment% just after %item-name%
%item-name%<p>%comment%<p>
There is no problem with a file comment, just the "folder comment".
Terayon does not use a single <p> tag.. and i even think you break the row if you use one.
No, this problem is not related to the [file] section or the icon generator, just the alternate row color thing. gimme a few more minutes and i shall solve this.
