Image preview displays and saves wrong image for Fireworks CS4 Mac

If I have multiple tabs open in Fireworks CS4 Mac and use the image preview dialog it displays and will save the wrong image. It will instead show an image from another opened fireworks file in a tab and then also save that wrong image.

I noticed this problem has been reported by others with no response in the adobe forums http://forums.adobe.com/thread/230631

This is a frustrating bugs as it doesn't let you actually work with multiple files open and use the export via the image preview dialog.
