When I'm working with Eclipse, I fill my main monitor with an editor and break out all the panels (Navigator, Console, Problems, etc) onto my secondary monitor.
I've noticed, though when I open a dialog (for example, Open Resource) then cancel it (eg, by hitting escape), the focus is shifted from the main editor window to one of the broken-out panels.
Is there any way to prevent this? Or, failing that, is there some shortcut for "refocus the main editor"?
