Guild Wars 2

1. Activate the mouse through opening a menu or starting a chat message, but don’t actually disable action camera.

2. Click on the down arrow on a chat tab to edit it.

Result: Your cursor disappears and action camera reengages, but pressing any buttons (including the button I have bound to disable action camera) types into the name of the chat tab.

Pressing Esc can get you out of the chat tab edit section, which then lets you retry without action camera.

I am also experiencing the ranger pet issue.
