What is it with that withdrawal issue on Poloniex. When I click that button, nothing happens

I been scared of exchanges for a few weeks now, leaving cash on them. I was lucky to have withdrawn my funds from polo before the event.
I know cryptsy has its issues, but its very good to have a large, trusty exchange backing our trading now.
Just made a huge worry of mine go away. Big step forward! Now to get more exchanges on board. We still have lots of work to do!
