I'm running Ubuntu 9.10, his computer is running Ubuntu 9.04. both of us are on 32 bit systems. We installed Sandbox 2.4.0rc1 from http://www.playdeb.net
Issue 1: Right click on the mouse does not jump.
Issue 2: We can't place new map models. I've included some screenshots of this issue:
First I select a square, then select New Map Model and Grass (or any other model)

And THIS is the result (I've manipulated the image to make it smaller by moving the selected square over closer to the error message)

Any clue whats going on here or what we are doing wrong?
thanks!
