Thanks for pointing me in the right direction.
As for "Mac-ified", I meant that Windows, since the beginning, has had two mouse buttons. Apple stuck with one. All other Adobe programs (to this point) made use of the right-click (hence one-handed) contextual menu. I use my wife's Macs frequently, often working on images for her jobs (she's graphic designer) on her computer. I miss my workflow of "right-click" when I'm on her computer, in many programs. So, my comment is not really about Macs, per se, only that Adobe has chosen to abandon a perfectly good way of working in Windows in favor of a comparatively more laborious shift- or alt-click. In all other programs, the right-button works as it should. In CS4, if I right-click the frame, nothing happens. If I right-click the ruler, I get the menu with options to change the units.
