Hi! I've only just installed the November update on an El Capitan system.
Is hiding InDesign currently not working at all or just not with El Capitan or have I got something else going on here?
Behaviour around hiding the application or bringing it back to the front, be it shortcuts, clicks with pointer tool or using menu commands is not working as expected (here).
I'd love to hear if I am doing something wrong as it's really annoying at this point
Try trashing your InDesign preferences.
Derek! Classic solution... I'm always hesitant to zapping the prefs (you're likely to miss something when re-configuring) but this did it! Thanks!
