PALPLE  I don't know about Safari crashing, but I can surely say that this isn't due to my widget, since you are only downloading a zip file.

As regards the exclamation badge it's because due to a problem with my server and I noticed that yesterday you downloaded the old version of the widget (0.4.1) and not the new one.

PALPLE  Well, the euro currency for the ecb list it's missing because it's the reference point of the ecb values, so it's the same as the other euro!

PALPLE  Thanks for your appreciation!

The currency data I use comes from the yahoo finance service, which is lively updated (with a 20 minutes delay).

The european bank data instead it's updated only once a day; I could create an option to use that data, but it would be inconsistent with the other world currencies data which comes from the yahoo service, so I don't know if it's a good thing.
