64 bit
Device Notifier has gone a little crazy.
I have two instances of DN running ...... one on the Desktop from where I can select to mount/unmount partitions, and the other in the tray, which reacts to a plugged in block device.
They have worked independently ..... on both 64 bit and 32 bit.
After the update (and reboot) today, whenever my mouse passes over the one on the desktop, it immediately reacts by expanding the entry it touched, and at the same time the DN in the tray pops up also.
If I use the mouse on either of the DN instances, and scroll down the entries, the other DN display follows exactly.
It is as if there is now only one DN, which is displayed in two locations!
Not good .......

I tested this with three instances of DN, and they all mirrored the one I moused over.
BTW, forgot to say that the ability to move the widget on the desktop has apparently disappeared too. Onece place it cannot be mouse-grabbed and moved.
(I know I was aware of something else to report but these popups have driven it from my mind
