[ka-Map-users] ka-Map map file list bug

[Paul Spencer]

yes.  I've been playing with prototype.js and it mangles array  
iteration using the for (var i in a) syntax by including functions in  
the resulting iteration.  I'll probably change how this works at some  
point to make it more resilient.

Cheers

Paul
