Hi experts! I have just installed Sketchup pro 7 with all correspondent plugins. So far, I have been working with an older version (Sketchup 6) without any problems but now I have found that anytime I click on the face of a prism in order to move it or just do something with it, instead of selecting this face, the next one is selected without any reason.
Do you think the problem comes from the pluguins or am I doing anything wrong?

Thanks!
