Exception with MmFile

[sybrandy]

Hello,

I'm currently getting a message stating that an exception has been 
thrown when finalizing an instance of std.mmfile.MmFile.  What would 
cause this?  I've used MmFile in other cases without any problems. 
However, in this case I'm using it as a member within a class.  I see 
nothing in the std.mmfile documentation that suggests that I need to do 
anything special.

Any thoughts?
