Keeping the correct focus on desktop switch

Hello everyone.

I'm using two monitors with Sawfish and MATE and the second monitor is
mostly occupied by stickied chat applications. Now in the last time I've
noticed that whenever I switch workspaces that the focus jumps onto the
second monitor, despite that a window on the first one was focused.

Assume the following:

 * Desktop 1:
   * Monitor 1: Browser
   * Monitor 2: Stickied applications
 * Desktop 2:
   * Monitor 1: E-Mail client
   * Monitor 2: Stickied applications

Now if the browser has the focus and I switch to desktop 2, the
stickied application get's the focus. Now I focus manually the e-mail
client and switch back to desktop 1...the stickied application has the
focus again.

Did I break something in my configuration or is it supposed to be that
way?

Best Regards,
Bobby.
