No problemo.
When i click on one of the 2 space navigator buttons, normally, like in any of the rest of my apps and in the Finder, a window pop up from 3dconnexion app. (a kind of pie menu)
That's just what i want : Emulate the 2 space navigator buttons.

Wanted to be polite.
This is not a request, this is a Blender bug : No Emulation of the 2 Mousse Navigator Buttons.
There is something in Blender that "overwrite" the 3dconnexion app.

Same here

This is The One.

Ok, solved with blender-2.69-b3bc9e4-OSX-10.6-x86_64.

Ok, i got it. (You have to select an object) Sorry for disturbing.Best regards.

In 2.69, i "de-toogle fullscreen"(blender in small window), then save it as "startup file", quit it, open blender-2.69-b53f310-OSX-10.6-x86_64 and it works !(Toggle fullscreen + the <-> appeared{F76395})

No problemo with other applications :

No.

When i press "Toggle Fullsceen", Nothing's change, no crash. Thank Thomas, i was looking for this<-> button.

Ok with Ray Pump.
It's when i enable "International Font" : i just can't open this build. Instantly crash.

Done.
Thanks again.
