Comma as a separation character messes with some localized float representation.

[loothunter1]

On some localized systems (e.g. mine) floats have comma(,) separating integer part from the fraction part instead of dot(.). Because of that separating parameters in GetSettingsString/SetSettingsString in SfxrParams.cs with comma(,) creates a string that isn't read correctly. Please, change that symbol to something else.

I hope, my explanation was adequate, I have limited programming knowledge and English isn't my first language.

Thank you.

Sounds like something needs to be using InvariantCulture that isn't. If that is a string being manually editted by the user they need to be entered as InvariantCulture.
