Way to go, Burak! Kudos! This actually works.
So simple and obvious, yet so elusive until now, until someone like you who
can remember to look for the obvious tried it.
I am sure the fact that this workaround works will give valuable insight as
to having a permanent solution. Burak, my kindest regards.
