My upgrade to Mac OS X 10.5 Leopard has been successful without any glitches. I had even spare time to update my iStocks Widget to v2.0. It is now ready for Leopard but works also in 10.4. It has some new features based on the feedback, including support for stocks, futures, mutual funds, indices and currencies like “EUR=X”. It has an integrated symbol lookup facility and ships multilingual. Check it out.
