The window you are clicking is responsible. It can request a focus
change and stumpwm by default will honour it.

Yes, firefox is the only program I know of that does this. It's
unrelated to your problem below.

I can't reproduce this.

I can't reproduce it, with this version either.

I'm not sure why this would happen.

Let's start with some basics: What architecture, what OS, What version
of stumpwm, What lisp version?

next does

C-t ' address@hidden

work? does this work:

C-t ; goto-shell

Have you tried removing everything but the above defcomand and
define-key lines from your rc file to see if that fixes it?

I guess we'll go from there.
