Try this - fresh boot
Open synaptic, should open in a typical default or so window size.
Maximize and then close synaptic
Open synaptic again, should open maximized, then click restore, it should only restore to slightly less than maximized
Grab the r. bottom corner of synaptic and resize to 'normal' windowed size
Then close synaptic and click on the power button > log out. At least here the confirmation box will not show (enter on keyboard will work though
If the above doesn't cause, then a slight variation - on my desktop I need to Alt+l.click and move synaptic up to be able to resize, then after the resize pull down to close. So same as above but move up then down
I can repeat this at will, hope you see the same
Also on unity opening update after synaptic (open/close) may also cause the same or crash the kuancher
