Hi eric, is it possible that the script for Alt+A is not set up anymore in your keyboard shortcuts?

Double check under Options > Shortcut keys, if it's not there then set it up from here:

If that's not the issue then can you please send the file to me at moi@moi3d.com so I can test with it over here?

Thanks,
