When I give a fraction as input in any of the number fields (I use fractions mostly in physical params), it becomes zero once I have apllied changes and reopened params window.
To be more precise:
If I enter 1.2 somewhere, the next time I open that particular parameters menu, there is no 1.2, but a 0.
But if I enter 1,2 - that is, with comma - at first is becomes 1.2 - with dot - and next time 0.
