Weird handle lock by tortoiseproc.exe log windows...

I had two svn logs open on local workspaces.
My tortoise settings have exclude *, include a couple local workspaces.
 
When I browsed to a network mapped drive to rename a folder I couldn't.
 
procexp.exe showed that each "tortoiseproc.exe" had a handle on the
directory I had browsed to (it is completely unrelated to any version
control directory/drive etc).
 
When I closed the two svn log windows I could rename the folder.
 
Weird.
