EasyChart: Dot considered decimal symbol

I have a problem with the easychart in ignition. When i cast a number into a float it interprets the “,” as a digit grouping (1000) and not a decimal separator. I am working with windows XP in which the “,” is defined as decimal separator in the regional settings.
The casting code worked fine in the easychart of PMI version.
Do you have any ideas to what i can do?

Exactly where is this casting taking place?
