Accept comma as decimal in input boxes

A user reports:
The language of Macro Studio is set to English, however my OS language is German. In Macro Studio, decimal values are displayed with a decimal dot, e.g. "1.6". But when i manually enter a decimal value into a input field, it ignores the decimal dot. so the "1.6" will become a "16". This is probably because of my OS language, since in Germany, decimal values are written with a comma instead of a dot. If I enter "1,6", it works as inteded. However after I press enter to confirm it is displayed as "1.6" again.
