Comment 1 for bug 746487

This report seems suspicious. You are talking about docky (which is not a window manager BTW), where the description in this report fits the default behavior, but the bug is assigned to unity, which DOES use compiz scale to present open windows by default.
Can you please verify this, by stating which ubuntu version you are using and if a docky or unity process is running, by entering the following command in a terminal window:
     ps ax | grep -E "unity|docky"
and paste the output here.

Thank you.
