InDesign – Out of Memory?!

I have a simple InDesign document at work that refuses to print …before it gets done flattening it says it’s out of memory, or something to that effect. The page has ~5 images on it and a couple lines of text. One image (the background image) is at 15% opacity …all of the other images are 100%. All of the images are Grayscale.

I have even deleted the image with transparency and it still won’t finish. I am running with the most current version of InDesign and I’m working on a dual 2.5ghz G5 with 4 gigs of RAM. …oh, and I can export to PDF just fine.

Anyone know what is going on?
