Thanks, I’ve fixed it.

Here is the latest patch. I added a customizable variable that controls
the default directory in where we store/restore window config file.

By now I’ve collected 3 patches: register, memory and store/retore
window config. They all seem to work pretty well but I haven’t used them
too much since I’ve finished my bomblab...
