I finally found  how to fix this.
1) drag an item from the Panel menu onto the desktop so that it can be 
examined.
2) It is set to open  with Theme Installer
3) Change the 'open with' to file-browser

On second thought I am not sure that this was caused by the security 
update or something I did inadvertently.  I don't remember messing with 
anything in the Panel menu, but it wouldn't be the first time that I was 
simply stupid.  While earning how NOT to use the touchpad on my laptop 
while typing, I am overcome by unintended consequences.
