Reported it in BETA & Live still here
Does this bug relate to the gem store? Does it relate to the Living Story? Is it an exploit? Is this something that people who buy gems with real dollars might actually get upset over?
If the answer to all of the above is “no”, then ANET will almost certainly never fix the bug. They’re ANET. They don’t fix bugs. Instead, they ignore them. This is so close to accurate that calling it an exaggeration would its self be a bit of an exaggeration, and it’s just plain sad.
Funny, I can hold down the Left Mouse Button and zoom in and out with no problem. Perhaps it is an issue with your mouse, or some other setting in-game or with your computer.
