In your newreply template, search for;

<if condition="$show['parseurl']"><div><label for="cb_parseurl"><input type="checkbox" name="parseurl" value="1" id="cb_parseurl" tabindex="1" $checked[parseurl] />$vbphrase[automatically_parse_links_in_text]</label></div></if>

Delete the $checked[parseurl] part. Then do the same for the other templates that have it in, eg: newthread.

That seems to work. I don't know if that's the best or "proper" way but it seems to work.
