When I hide a window using /window -h, it hides the window from the treebar/switchbar.

Though when I check $window(name).state, it says its 'minimized', not 'hidden' as it used to.
Also, if I hide it using /window -w#, it hides it as well, but the state is 'normal', not 'hidden' or even 'minimized'

Sounds like this is related to this post

Thanks this has been fixed for the next version.
