alice-teacher Error when attempting to add an object to a world

[Grim, Dianne]

Don,

A few of my students are encountering the message:  An unknown error has occurred

when attempting to add an object to a world using Alice 4.x

The object is selected and the specifications for the object appear.  Students selects 'Add instance to world,'  the camera pans to where the object should appear but nothing shows up.  The error message is then shown.

Could this be computer specific?  All of these students are using a PC laptop when this occurs; this error has not yet shown up on the MacBooks.

Thank you,

R,
