multi currency

[Blood Angel]

I use multi currency (RUR&USD) on main screen (overview) balance summary is RUR+USD (e.g. 8000RUR, 300USD= 8300 RUR), but 1USD<>1RUR how to change it?
and the second: if i choose not default currency, all category are in this currency, but accounts aren't this currency

In order to understand how iCash handles currencies I recommend you to read the following "How iCash applies currencies and rates?".

About second question, categories and types are always converted to default currency. Only accounts can have different currencies.
