[Glitch] Talking in Numbers?

I had that problem last night, I didn't know what was happening. I first thought that numlock had came on, but it wasn't that. So I then relogged.

Was amusing, because the person that I was trying to talk to (a total stranger) then whispered me when I logged back in to tell me that it was a weird glitch that had been happening (I think it was quite obvious I had no idea), and that they didn't think I was crazy

And LOL Tess (and others that it happened on Z-Runs), that must have been quite amusing
