pack n go

I just installed 2009 SP2.0 and now the pack n go does notfunction correctly.
The part names in the new assembly tree do not update. If you openthe part from the tree it does open as the correct part. Even if Isave it and go back to the assembly it still shows the originalpart number from the pack n go.
In the past it was a mater of hitting QTRL Q and then the partnames would update.
This is now not the case. I even checked the references beforeopening the new assembly and it was all good.
This was not a issue in the previous service packs.
So my question is , What the @&\\\$%???
I use pack n go often so any suggestions would be appreciated.

Over all SW2009 has been a big disappointment. 2008 was more stableand quicker.

Thanks
