sketch will not show in part

I can create a sketch but when I go to show it, as in creating a sweep, I cannot view it.

I cannot select it in the command. I can preselect it from the tree but it does not show.

The show hide command does not appear to be working correctly.

I am using 2011 sp4 windows 7 64bit.
