I use background images for modeling in Blender 2.48, and if I use the navigation keys to look at my model, the background image disappears and I'm in a different top view, with the top camera a little to the right.

Is there a way to fix this?
(yes, who cares if I like using blender 2.48. I have 2.5, as you can see in the dock, but it's so different the Blender For Dummies I own is obsolete when It comes to blender 2.5.)
