Does anyone use WindowMaker?

I do, installed it on netbsd 1.4 for i386.
In the very left above is an icon, it is called here main.
When i click the right mouse button and do rename workspace i can chance
the name. However, if i reboot x then name is main again..
How can i make that change permanent.
And, is there no text file i can change so that i can change the name main
in there? how to do that with xprop?
Bye,

Reinoud.
