question for people who own the 580EX II

Hi,

I just bought the 580EX II, I have a question about the lock lever that locks the flash to the body. The lock-release button, which you use when you slide the lock lever to left to detach the flash, is not very thightened, it moves alittle bit, but only when the flash is unlocked.

Can you confirm it's ok?? or it should always be thightened?

Thanks a lot!!!
