Does Adobe PhotoShop Elements 10 Support Dual Monitors? Bing searching only seems to provide links for how to setup dual monitors in full blown photoshop.
Lightroom seems to be aware of the existence of a second monitor, and has specific menu actions for placing windows there. However, a program doesn't have to be aware of dual monitors, as long as it has child windows that can be moved around outside the main frame, they can be moved across into a second monitor. It's handled by the operating system and display adapters, which is most likely oblivious to the fact there are two monitors involved.
I don't use Elements, but it seems to have dockable, movable palettes and toolbars like Photoshop CSx, so I would imagine the answer is yes.
There is anecdotal evidence in this thread that users have been using dual monitors since Elements 7.
