Hi Michael,

>Can you please send me an e-mail at moi@moi3d.com and I'll send you a build with a fix for this to test.

I just sent you my e-mail.

About the alt+o shortcut, I never thought to check in the existing shortcuts.
I deleted all of the standard Edit Shortcuts that already have equivalents in Ctrl or Cmd and it's OK.

Thanks again !
