Why does the following happen?
Installed 2011 SP05 thumbnails disappear.
Installed 2012 thumbnails available.
Installed 2012 SP01 thumbnails disappear and could not get them back.
Installed 2012 SP02 thumbnails back again.
This also happened all the way through 2011 install a SP they would disappear install the next SP they would be back.
Now they are back I am reluctant to install any more SP incase they disappear again.
Oh and when they did disappear I tried a reg edit with no luck.
