Why can't I paste URLs into posts anymore?

Seems to be working OK for me... Have you tried a different computer/browser? For a long while now I've had a weird issue were certain computers will not let me pase anything into the forum here, but everywhere else works fine... (The same 'issue' apparently stops the Quote button working, too...) If it's on everything... Sorry :/
