Leaving aside the pontificatory apoctypha for a moment -

Funny. My download of the same package shows that it starts up with the expected behaviour of the right button raising a menu and the middle button opening the halo. This is as expected and as has been the case for a long time. It happens to be the *wrong* way in my opinion since quite obviously a middle button  (and all mice should have three, clearly) ought to open the contextual menus. However, the preference is trivial to find and many unfortunates are inured to wrong way through a sad life of deprivation and privation whilst using inferior systems.

Halos have been part of Morphic since before the dinosaurs roamed the earth. They are not an 'improvement that made Squeak as worthless as a balloon full of machine gun holes. ' that has suddenly been foisted upon you by those of us in the elite {strokes white Persian cat while glaring at you from the Volcano Lair(™) on my secret estate on a Pacific Island} as a way of ruining your morning.

For the right button to open a halo would require
a) the preference being set that way in the release; which it is clearly not.
b) the preference having been set by the user, either deliberately or accidentally
c) the preference having been set previously, saved and then loaded by the user
d) the device’s mouse driver being swapped
e) use of a vm flag such as ‘-swapbtn’ on unix and probably others on Mac/Windows.

I’m glad I didn’t go to a college like that.

>  I can't remember the Halo ever once being useful.  Take a class in SolidWorks and do that in Squeak instead of Morphic an other not useful improvements.

The only useful part of the Solidworks UI I ever found was the exit.
