Hi Brian,

I am sure you already tried the usual things like

• reset your preferences
• checked if you have undocked your tool bars and arranged them somewhere else
• turned the tool bars off and back on

What happens when you change Carrara to Window Mode and then change the size of it's window to very small, so the tool bars are forced to be rearranged?

I guess the black line is the handle of the VM selection tool bar.
What happens when you drag it somewhere else?
