title: What minimum screen size should I assume?
body: <p>I'm designing various unsizeable forms and layouts in Delphi to run on Windows.  I'm worried that if I assume a minimum 1024x768 screen size (or greater), I'll run into customers still using 800x600.  What minimum screen size should I assume?  I don't want to require a minimum that irritates users.  What's the best practice or current reasonable assumption for screen size?</p>
