Still something wrong with the gadget..   When you select trading mode, and then back to mining, the url switches back to old url.
Also, this gadget won't work with correct url manually entered also.

I located the problem in the "Settings.js" file.  Even your new version has this error still.

I "fixed" the js file with the proper url "http://data.mtgox.com/api/1/BTCUSD/ticker" in two places where the old url was, but the ticker still doesn't work for me at all. (although after fixing the settings.js file, the url now always shows the proper url, but the USD box always shows N/A, for both mining and trading.   If I choose mining, I get N/A in both BTC and USD boxes too.

So I tried to use as my exchange url: https://api.bitfloor.com/ticker/1
I entered into the exchange rate JSON key: price
And deleted all other entries below.
And now it shows USD value properly.

Something is messed up majorly with the new version and the new mt.gox ticker url and JSON keys that its using.
