Comment 3 for bug 861088

I can't confirm with ctrl-alt-arrow but what I can see is the dialog I click on being hidden and then displayed again in the desktop expose

example with 2 workspaces:
- open gedit on ws1
- open firefox on ws2 and open another gedit on top of it
- click on the unity launcher workspace icon
- single click on gedit in ws1, you can see the background image (i.e gedit got hidden) for a second then gedit comes back
- single click on gedit on ws2, you can see firefox displayed for a second and then gedit coming back
- if you click on something already focussed it doesn't happen

it seems it unfocus or hide the dialog you select before selecting it...
