Lamagra - it could be any number of things, but this hack shouldnt affect a lock routine... what other hacks do you have installed? and can you top and detop topics?
gohaku - you need to edit your current style template from the cp. down the page you will see the place to select graphics for delete thread, close thread, etc, and there will also be 1 for detop topic and 1 for top topic. enter the gif names (ie: "detop_topic.gif") in those boxes and submit.
MrStormyNights - you need to upload the file public_top_topic.pl from the zip to your Templates directory.
TaPaH - try the one at the top of this (the 2nd) page.
