Just how did you perform the switch?  The opam switch statement updates 
definitions in your ~/.bashrc and a few others.  When you start a 
new shell that runs this file, you won't fully be in the new 
environment.

There is a command that does this  update in the same shell, but  frget 
just what it is at the moment.

(I'm saying this from a Linux perspective; I presume that cygwin is the 
same.)
