Bug Description

Docky 2.1.2 on Ubuntu 11.4 Natty (Unity) on Lenovo X301 (2776) laptop, Intel HDA graphics, Intel 4500MHD, with external second display. Screens in top/bottom arrangement, laptop is primary/bottom screen and external screen is secondary/top.

Two problems, one just an annoyance, one a total failure:
(1) Switching from one monitor (laptop) to two monitors (laptop botton, external top) with xrandr, Docky switches to top/external monitor. Not sure if this is a bug, but it is undesireable, leaves Docky in the middle of the combined display. Can click on 'anchor' and drag it back down to botton/laptop/primary monitor.
(2) Switching from two monitors to one monitor, Docky shifts from disconnected top monitor to bottom/laptop/primary monitor - how it not longer works, it no longer registered any mouse clicks, it no longer auto-hides or react to other windows. Otherwise it appears to still be running.

Let me know if there is any addition info I can collect or tests to do.

[Easy answer would be to blame Unity rather than Docky? Natty/Unity appears to have been released with zero consideration or testing on multiple monitors. Only two days in, and a long list of bugs to report like this. Guessing people at Canonical are not allowed to use multiple monitors :-) ]

After (2) occurs sending SIGQUIT I get this:
