image in a long task causing PDF output to overlap text

Hello,

I have an image in a 10-step task/procedure/step/figure 
(screenshot/mediaobject..) that appears to be causing PDF output to 
overlap text on the page containing the task. I would guess this has to 
do the keep-together processing instruction, but I can't seem to solve 
it. I tried:

	<?dbfo keep-together="auto" ?>

as a child of task, procedure, step, and figure, with no visible change 
in the rendering.

It's also odd that when the page is scrunched, it still leaves a 
couple-inch-high gap below the image that ends the task.

I'm using db5, ns-1.73.2 DB stylesheets, and Apache FOP 0.94.

Any help greatly appreciated.

Thanks,
Brett
