Usually, when I open a CS4 InDesign document by double-clicking its icon (Mac OS X Snow Leopard), the resulting document window is well behaved and sits just to the right of the toolbox panel and is sized so that its right edge is just to the left of the various panels down the right of my screen. Its top margin is just beneath the control panel across the top of the screen and its bottom edge is clear of the bottom of my screen.
Recently, however, I have had several instances of the document window being less well-behaved. Its left edge is hard-up-against the left edge of my screen and tucked beneath the toolbox panel and its right edge is hard-up-against the right edge of my screen and tucked beneath the various panels there. This makes selecting objects behind those panels difficult. The top edge can be up to about 7-8mm below the Control panel (who needs a gap there?) and the bottom edge (which, of course, contains all those useful navigation buttons) can be hiding partially-hidden beneath the bottom edge of my screen. But this does not always happen. Curious.
Have I overlooked some setting somewhere? Does the fact that I am using Soxy have anything to do with it?
