Hy everybody, I have encountered the same 'error' and my solution was to make all stuff on Maya 6, because fewer bugs and all my plugs and scripts work just fine. Maya 7 has A LOT of errors, and since Maya 8 has nothing but some stuff that everybody with knoledge of API is capable of doing in some scrips, i doubt that the "great" Autodesk fix them. I am wondering how much we will have to wait before they do something well. Let's hope....
