I've thought about this myself. The middle mouse button isn't needed for
any critical actions in our desktop UI as far as I know, so even if the user
had a two-button mouse, they would be OK without emulation. If middle mouse
button actions are important to someone, they're likely to have a three
Of course, this is configurable, and it's only a matter of what to choose by
default. The question is, which is more common among (potential) users?
Games of this type, or two-button mice? And which group should have the
burden of changing the default?

My mouse has a fourth button, but I've never configured it to do anything.
However, I don't see any reason why it shouldn't be set up to generate an
event by default, so that the user can assign it an action if they want.
Please file a severity: enhancement bug report about this and we'll see what
can be done. If you can include some of the information and references
you've collected, that's even better.
