Resizable dialogs are important, especially when you have any scrollbars.
If a dialog has scrollbars, it should also be resizable and save the last size & location it was given.
Windows Vista’s wireless network dialog below is not resizable, yet it often has more entries than I can see at one time. Wouldn’t it just be easier if everybody could use the <Grid> element…
