It is possible that the version you are using is causing issues. I am testing with version 3.8.12556 which is from 5-NOV-2012 (a newer version came out yesterday afternoon but I haven’t upgraded my machine yet).
I tried adding a new form and added a grid on it, and this is what it looks like for me (see attached screen shot).
If you want to upgrade to a newer version, please visit our Updates Center
