Hi all,
sorry for not updating sooner, was offline until now. Yep, MtGox turned off http API and started redirecting it to https, and IE which has to be used in gadgets unfortunately doesn't follow redirects. New version of gadget is available for download, but you can simply change exchange URL to
https://data.mtgox.com/api/1/BTCUSD/tickerA few quick tips on API changes (and MtGox seems to change API pretty often). If gadget stops updating, you can force update by going to settings and clicking OK without changing anything. If you see N/A, then one of the URLs that are polled is not working - try loading them manually in browser to see which one. If you understand JSON you can also figure out if JSON changed and update accordingly and please feel free to post it here for others to see.
Gadget is completely configurable and should work with most APIs for precisely this reason, APIs change and exchanges come and go... and hopefully we'll see more people using alternate exchanges so that MtGox doesn't hold that much of BTC exchange traffic and stops being the central place for attacking decentralized currency.
Actually, let me give some settings for alternate exchanges (just change it in settings):
