as I understand it, David: please correct me, the problem 
is the following:

The regional settings (in a german windows xp, this can be 
found here: 
Start->Einstellungen->Systemsteuerung->Regions- und Sprachoptionen
english might be:
Start->Run->Control <Enter>  Regional Settings?)
define number formats for user interaction (see attached 
screenshots).

I personally appreciate that BlackBox does not follow these
settings (neither in forms nor in the program source), but
I can understand that someone asks for being able to have
forms, which allow for localized settings. 
It is sometimes very difficult to force naive users to use 
international standards. Additionaly: the key between zero
and Enter on the numerical keypad enters a comma with a german
keyboard ...

I don't like the idea of having programs using 1,0  for a 
floating point 1.0  ...

regards
