I have a bug with shortcuts alt+cmd+space, or cmd+space or space for the zoom tool with photoshop or illustrator. my system is MAC OSX 10.11.1
This bug appears sometimes, and sometimes it not appears..it's very annoying.
Please Have you got a solution.
Are you, by chance, using a tablet on your computer? How about an unusual mouse? Do you have any applications that grab screenshots or sounds, particularly DJings applications? What about sidecar applications that accept character input when another application is running?
I ask these questions because what you're describing sounds like another app or tool is sometimes stealing your keyboard input. This is actually more common than you might imagine (*grumble, grumble* lame testing strategies...). Hopefully, what you're encountering is caused by one of the above and you can simply shut down the offending app or tool.
If this doesn't solve things, let us know and we can dig more. For what it's worth, I use these shortcuts all the time on my machine without troubles.
Hello David, Thank you for your quick answer. Yes I am using a tablet wacom intuos 4 and a classic magic mouse 2. I have no application that grabs screenshots or sounds nor DJing applications. I'm using a font manager : Suite Case fusion 5 which is my first suspect, but the problem appears even when it is shut down..( I mean really shut down, with no background task). All the other photoshop & illustrator shortcuts are working properly except this "essential one", which is working two times out of three..:( The problem is that is random, I don't manage to reproduce this bug.
