One more thing, if left mouse button value 1 and right mouse value 2 are excluded, AGI Mouse, NAGI and ScummVM have all more or less different reactions and values for mousebutton combinations and different mousebuttons, so if there will be changes, could you please try to unify the values little bit for ScummVM, would be easier for any remaining AGI game developers.
Here's a list of different interpreters and their reactions to mouse:
AGI Mouse 1.1:
Left button 1
Right button 2
Left + right 3
Middle button 4
NAGI 2.09 (with SDL 1.2.14.0, originally supplied with older version 1.2.9.0 which did not support Windows 7 so well. It started to register thumb buttons only after the latest SDL):
Left button 1
Right button 2 for moment but if pressed longer 4
Left + right 5
Middle button 2
(Logitech MX 518):
Thumb button 1 32
Thumb button 2 64
ScummVM 1.2.05:
v27:
Left button 1
Right button 2
Middle button 1 or 2, depending which has been pressed later
v19:
Left button 1
Right button 2
Wheel forward 3
Wheel backward 4
And then while testing, all the sudden, this appeared out from nowhere:
