It looks like any time any slider is focused all the values get 
rounded to the nearest slider "tick".  Slider ticks, for floating point 
controls, come every 1/1000th of the range.  Meanwhile the display 
values are rounded to the nearest thousandth, hundredth, tenth, or 
unit depending on the range.  If the range is 0-30, for example, 
display values are rounded to the nearest .1 and ticks are every .03.

Steve, you're comfortable applying patches and building from source, 
right?  I'm attaching a patch that might fix the problem, although I 
don't know enough about Nyquist to know whether I did it right or not. 
The basic idea is that it sends what was written to the text box 
instead of the floating-point value. It doesn't work if you enter 
something that doesn't look like a floating point number into the text 
box, which should be fixed, but I just want to make sure I'm doing it 
right in the first place.  If you can't build I'll try to figure out how 
to test Nyquist stuff tomorrow.
