Don't know why passing just the window name doesn't work.

Because the author didn't think to implement it?  He will
accept patches though 8-)

If you are going to attempt this, you should check not only
for strings, but also for typeinfo(window)=="function handle"
(there is no 'isfunction' call, and 'exist' only accepts strings).

Out of curiosity ;-), under what circumstances would typeinfo(foo) return "function handle"? I only see "string" or "matrix" (i.e. the return value of window(n)) in this case.
