Setting Split form Window Sizes

I can't get A2007 to remember any Split form window sizes after trying
various options for the last 4 hours I've had enough, this should be simple.

I've got Access options set to overlapping windows.

I've switched off Auto Resize and Fit to Screen.

I've tried saving the form after I've sized it to how I want.

None of the above works - I can nearly get it to work if I set the "Split
Form Orientation" to Datasheet on right, but it's still not how I save it!!!

If I set the "Orientation" to below it's nowhere near and sometimes it isn't
even a window!!!

I'm about to give up and try Open Office!!
