click on thread title leads to the print version of the page

Something weird is happening with a thread in the software forum. If you click on the thread titled "Help, draftsight to gimp to print", instead of the normal page you're directed to the print version of the page whick lacks a reply button. Not that I could help the OP.



It's a rather strange issue. Could it be because of the last word in the thread title? I've tried Firefox 29, Chrome and IE 9 with the same results.
