I'm having problems changing the decimal separator to a period in Tracker. Every time I go to 'preferences' and select 'period' as the decimal separator it keeps reverting back to either the 'locale default' which then displays a comma. My language is already set to English which I can see from previous posts can be an issue. Its not a big deal but it makes things difficult when copying and pasting data in Microsoft Excel.

Any help would be much appreciated.
