[pmwiki-users] how to hide "browse", "edit", "diff" etc from title bar?

[Lerner]

Hello,
How can the words "browse", "edit", "diff" ect. that appear in the  
browsers title bar be turned off/hidden? I am using pmwiki-2.1.27.  
Any help or suggestions would be greatly appreciated. The enclosed  
URL is an example of what I am trying to hide.

The page title reads
"Cornell Assemblies | Krause Report Comments / Group Title browse"

I am trying to accomplish
"Cornell Assemblies | Krause Report Comments / Group Title"

Thanks in advance,
Derek
