Don't know if it's just me, but after the upgrade to El Capitan, my red quit button on the top left of the window is greyed out. So I can't easily quit Moneywiz without going into the menu.
The minimise and full screen still work fine.
I have the same problem with El Capitan. I guess it will apply to everyone. "cmd+q" (command/quit) exits OK.
I have the same problem.
Same problem here.
I confirm this problem. With that, in full-screen mode, the button appears and remains in place after the transition to the normal mode.
Thank you for reporting this. We are aware of this issue and working on fixing it for the next update.
