[Etoys] 2 button mouse confusion

Hi,

Have just switched over to a recent EToys image (about this system says EToys 3.1 latest update 2177). I have a 2 button mouse (well, a touchpad with 2 buttons underneath), and I want to access both halos and context menus.

Something has changed in this area since the last images I was using.

By default, right button now gives me a halo. So does Alt-left-button. I don't know how to get a context menu up now.

If I swap buttons 2 and 3 in the preferences, (and this is the new and confusing bit), while right button now gives me a context menu, so does alt-left-button. This alt-left-button menu used to always give halos, I think.

So, how can I get a context menu up with the default mappings?

cheers, Simon
