Hi Costas,
By "2 Portfolios", do you mean 2 different sub-portfolios within a given portfolio file (*.mm4), or do you mean 2 different portfolio files? Typically you would work with only a single portfolio file, and use sub-portfolios. If you have 2 different portfolio files, each one will have separate currency settings, so you would want to verify they are both set the same.
If you do mean 2 sub-portfolios, then you can check the investment properties of the one that stays in the assigned currency. Make sure it is not set to an investment type of "Exchange Rate Investment". Also, verify under "Options / Currency Settings..." that it is not assigned as an exchange rate investment. In both these cases it will always stay in the assigned currency.
