With active focus stealing prevention, if I click on a window in the panel's task list, the window does not get focused or move to the foreground. Instead it just gets the alarm flag set (in my case the font gets bold). If I turn of the focus stealing prevention, everything is back to normal.
I can't reproduce this. Can you elaborate on how to reproduce? What apps, what arch?
This is on x86_64 (gentoo). It happens with all apps (Terminal, firefox, xchat, settings manager). It's completely reproducible here, as soon as I turn it off it works, if I turn it on it fails. Not sure what else I can say to help reproduce it... I just tried, the focus model and raise to click setting don't make a difference. I don't think I've changed much beyond that, but there might be some other setting I'm overlooking.
I just upgraded to beta1 on my debian machine, and I can't reproduce it there either. The weird thing is that even in a fresh user account I can reproduce this issue here on gentoo.
