Given Peter's explanation, setting options(Rcmdr=list(tkwait=TRUE)) before loading the Rcmdr package might allow the Commander to work (although it will disable the R command prompt while the Commander window is open). Not a good solution, of course.

tkStartGUI is just a proof of concept and many parts of it are sketchy. It doesn't create scrollbars on unix either, but you can scroll with the middle button (now how do you do that with a single button mouse?). It would be easy to add the scrollbar, I just don't think this is due to bad interactions with Aqua in particular.
Starting yet another console to get Tk windows to respond is just wrong. Presumably, the case is that nothing is running the Tk event loop and that tkStartGUI executes a "wait variable" which runs the loop by itself. It should be fairly easy to wedge a tk event handler into the Aqua loop (disclaimer: I don't have access to a Mac, I'm just assuming that Aqua works like other GUI toolkits and allows you to define idle handlers and the like).
