Ok well for some reason the drop down box has never worked for me in Opera, so I just fixed it
Not sure why but Opera never liked the line
var thelink = "http://www.techimo.com/forum/forumdisplay.php?s=%26forumid="+cmd.options[cmd.selectedIndex].value+"%26daysprune=1000";
it always says specified forum does not exist.. so I basically simplified it and changed it to
var thelink = "http://www.techimo.com/forum/f"+cmd.options[cmd.selectedIndex].value+"/index.html";
that works great for me
I think OuT sabotaged it against Opera!! We ALL know he hates Mozilla's competition!!
