Master Palette Kills Session

Every time I click VIEW-> MASTER PALETTE Muse Score halts.
I have used the 'repair' feature to no avail. I have downloaded
and installed a fresh copy and I still have the problem.
I have been using this version (2.0.2) for a long time and this
just started happening. I have rebooted my computer a few times
as well.

I am running on Windows 7 Professional.
