No, the QT and HTML wallets work perfect. I actually installed the latest QT wallet on a friends machine yesterday (running Windows 8 ), it took around 20hrs from start to finish to fully sync, then when it was, sent coins to it which arrived super fast (under 5 seconds!) and i know they have been buying coins last night and today ad sending to wallet and are very impressed with I/O Coin, to say the least.  

On the exchanges i am seeing slow build up of buy support, some real stealthy buying going on, very positive signs!

The next few weeks i can see IOC in the 7k region no problem, still a fraction of it potential value, which i expect to be in the 100k region within 12 months from now.  (write this down and thank me later!)
