I’m one of the thousands who are struggling with the use of Spaces and the locked up keyboard. When I use my keyboard to move between spaces, the Spaces image remains on the screen, freezing up my keyboard so that only limited buttons still work. The most effective way I’ve found to combat this is to open Activity Monitor and quit the Dock, thus giving me full control of my keyboard back again.
However, in the past 24 hours I’ve discovered something that I thought might be of use to someone with more insight into OS X than myself. I’m a Kensington Mouse user of more than 15 years. Their Mouseworks software allows one to customize mouse clicks in any way they see fit. Yesterday I noticed that when I go into the Mouseworks preference panel and indicate that I’d like to define a specific command for this or that button, that once I click in the space that allows me to type this command, my simple click therein immediately publishes anywhere from 1 to a half dozen characters, without my command. It’s almost as if somehow characters are being stored in my click. For example, I just clicked in this box and without me touching the keyboard, the letters Q and W suddenly appeared therein.
How does this relate to Spaces? A few hours ago when Spaces locked my keyboard, I went into Mouseworks and tried this again, and when I clicked in this box which displays any command accompanying my click, only the letter Q appeared on its own. I then canceled out of this box and pressed the letter Q on my keyboard, and Spaces unlocked! Suddenly my keyboard was free. A short time later Spaces locked on me again. Going back into Mouseworks, the input box displayed, “Q W Up Arrow” after I clicked therein. I exited out and pressed each of these keys and Spaces freed up again.
While I am a lifelong Mac user, I’m not an expert by any imagination, so I don’t know what any of this means, definitively. It appears to me, nonetheless, that for some reason, letters and commands, keyboard keys, are somehow lingering into my mouse clicks, and it appears as if Spaces is freezing my keyboard because it’s waiting for those buttons to be pressed.
Is this a keyboard error? A preferences error? An OS X error? I don’t know. But I thought that if I shared my findings here, someone might be able to look into solutions that I can’t conceive.
