What's the difference between an "issue", a "problem" and a "phenomenon"?

Canon uses all the above terms when addressing firmware "gremlins"!

Man, I hope this actually fixes the problem I've had since the last firmware update: Every time I turn the control ring (whether on an RF lens or on the EF-to-RF adapter with control ring), my C70 enters or exits record. One click = record. next click = stop record. Man, I hope this firmware solves it. It has been super, super annoying.

Well, I'm going to go ahead and quote myself here. I did the firmware update earlier this afternoon, and it fixed the problem! Thanks, Canon! I have to say I wasn't really expecting this, as it seemed to affect so few of us. Very pleased right now - I can go back to using the control ring again.
