Workaound: How to export from Prism Mac if the Export button at the bottom of the Export dialog is off screen.

In some cases, when you click the Export button on Prism Mac, you'll see a screen much like this (this shows the entire screen).

You can't Export because the bottom of the dialog, with the "Export" button is off screen. This is a new problem with OSX 10.3. When it opens with the dialog expanded to show the file list, it decides how big to make that file list so the dialog fills the screen, but it somehow miscalculates and the bottom part of the dialog is off screen.

It is easy to resolve this situation. Click the button near the top of the dialog that removes some of the details. 

Now you'll see a smaller version of the dialog, which includes the Export button.

If you now click that same button again to enlarge the dialog, it will be higher on the screen, and you'll be able to see the Export button.
