ctrl+shift+tab to unhide doesn't really work?

I have a short cut for this on my spacepilot. It would show all the hidden surfaces and bodies, but if I click on one to unhide, most of the times it would not unhide after I let go the ctrl+shift+tab. I would have to do this a few times before it decides to work. Very frustrating, are any of you experience the same issue?

I've tried both the short cut key or keyboard, same results.

Thanks!
