Viewer and Viewer Tool bar Bug issue

Ive noticed a few bugs once I switched over to studio 8.
My viewer tools on the bottom of the viewer are no longer visible unless I
remove the left viewer and only the left viewer.
crashes quite often when trying to resolve the viewer options.
Once the left viewer was removed i tried to toggle between the different
layouts and having to viewer screens freeze up not allowing me to do
anything in those viewers.
Just all around weirdness ive never witnessed during the beta.
Please help me resolve this issues.

Thanks.
