Wallet needs some GUI fixes.

For example, after entering a wrong amount in the "exchange", I got a useless error message.

"Place Big Order:"
"misc error"
..and No Cancel button !!!! OMG !!!

And then I see "balance: ? HEAT", and "balance: ? BTC" on that same page.

Using Heatclient_Setup_1.0.6 -- on Windows 7.
