wily in cygwin

I just started using Wily and had some questions/comments.  I'm running 
it in cygwin (which is probably the source of my problems).

Is it supposed to display "$PWD" in the tag?  Seems like that's an 
expression that should be evaluated somehow.

If you have a file named "new" (lowercase n) and you middle-click "New" 
then it opens the file "new".  What are the odds that a new user, trying 
wily for the first time, had a file named "new"?  Well it happened!  It 
makes for a very confused newbie.

Shouldn't I be able to right-click on "../" and open a window in the 
parent directory?

Anyway, thanks to the developers.  Wily promises to be a really 
productive environment.
