Comment 5 for bug 500981

onox, the 'setting' he is meaning is internal of AWN, not Gnome. The setting you mentioned affects the delay of usual windows before they get raised, in combination with the autofocus on mouseover ("Select windows when the mouse moves over them"). Setting the latter is enough to trigger the bug.

Note: Now I feel sorry that I didn't left a comment upon subscribing. Apparently that is necessary to raise your attention to a neglected bug. But thanks that there is finally some activity on it!
