Dashboard unit calculator

hello, i am new here.
although i have been using macs for many years, but i feel that i still don't know much about all the different functions on OSX.
anyway, i was trying to figure out the currency exchange the other day and found that the unit calculator for currency is not working!
it was giving me numbers that are completely off! (even the same currency exchange is not '1'!!)
i am wondering if there is anything i can do to fix it.
i have tried restarting the computer, making sure it is properly connected to internet etc...
my desktop is working fine though (within the same home network).

any advice is appreciated.

Safari 4 Beta breaks he currency converter. If you can't live without it, uninstall the beta.

Also, this is not the place for this kind of question. Moving to a more appropriate forum.

thanks!!
