Display problem in Views

I'm pretty sure you're looking at a cached View. Nevertheless, I'll update the module to invalidate Views' cache whenever the decimal and digit group separator settings are changed.

I've found it.

The problem is that both separators are widget settings. And a widget is designed solely for input. Thus it makes sense that the widget settings aren't loaded for Views. "Why are they loaded for normal 'views' then?" is another issue. I'll move both settings to the field's settings, where they really belong, and it should be solved then.

I'll fix this tomorrow.

Fixed. I'll tag a 1.2 release in a minute.
