That must surely count as a bug and I'd hazard a guess that it happens  
because some code is comparing floats; I've not looked at the code but  
I've seen it too many times not to suspect it.

As for your input widget, I'd try to make it give you the string and  
directly convert that to a 2dp scaled decimal rather than letting it  
give you a float. If there isn't a String>asScaledFloat: type method  
then I guess you get to write it :-)
