So what, you say. In many cases, this content difference will not matter, like in the example above, where the dialog is used to display scrolling text. Here's a real-world example. IE4 The Cancel button on the bottom right is cut off and all the elements close to the bottom are not spaced elegantly. A true application-dialog look with no status bar and correct spacing.
All elements are positioned elements of course.
Now it's evident that allowances must be made in dialog heights for the two browser versions, if the same content is to be visible in both and IE5 is to be lacking a status bar. Solution Create a taller modal dialog, conditionally, for IE4 users, using one of the methods below. There are other ways to size the dialog, and you can choose whichever method you are accustomed to, as long as your IE4 dialogs are taller than the IE5 versions.
