The problem with your info.ss was that it contained a stray $A0 
character.  The difference between DrScheme and MzScheme arose because 
DrScheme (apparently) expands the info.ss, where mzscheme doesn't.

I also notice that the error message I received when trying your file 
was considerably more informative than the one you posted, which 
suggests that error reporting has improved between the version that you 
were using and 203.3.

hope this helps,

ps. another reasonable request might be that drscheme treat all 
characters which appear as whitespace in the definitions window as 
whitespace in the evaluation of the program.
