MaBaSoft has released version 3.1.2 of Currency Assistant for Mac OS X. In the new version of the conversion calculator (http://www.mabasoft.net/products/currencyAssistant.htm), you can now automatically look for rates on the other web sites if they're temporarily unavailable on your favorite source. 

To automatically look for rates on the other web sites, select the "Try other sources if the rate isn't available on favorite web site" checkbox in the Rates Update pane of the Preferences window. The maximum precision of exchange rates has been increased in Currency Assistant. Rates can now have up to 12 significant digits. Also, rates updated from the IMF web site now have the same precision as the published rates.

Currency Assistant lets you convert between 174 world currencies (all major circulating currencies plus the 16 Eurozone legacy currencies) and automatically updates exchange rates over the Internet using the rates published by the European Central Bank, the Bank of Canada, the International Monetary Fund, and the Bank of Italy.

With Currency Assistant you can create multiple converters and manage currencies, import and convert series of amounts, calculate and convert the result of expressions, and quickly log, save, export, and print your conversions.

Currency Assistant is Universal Binary and runs in English, German,French, Dutch, and Italian. It costs US$19.95 for a single user license. Version 3.1.3 is a free update for registered users of version 3.0.
