First Idea:Resizing the window (by displaying a different set of layouts designed for smaller screens) is absolutely possible.
Second Idea: actually 'changing the screen resolution' of the monitor could cause other issues...depending on your user's OS and Display.....but I'd fathom it could be accomplished by triggering an external OS script (i.e. applescript or system shell script)
It is the screen resolution that needs to change. The only way to fit everything on the screen is by resizing it up to the higher resolution (1024x768). I figured an external OS script was my only option. Thanks!
