You may want to check whether the calculation of nZoom for a given
rZoomRect is broken, or if the rZoomRect given to
ViewShell::SetZoomRect() is wrong. The later I find more likely.
As for rZoomRect being different every time: this is especially during
start up when creation of tool bars and child windows leads to multiple
resizes of the center pane. You somehow have to sort out the calls to
SetZoomRect() that originate in resizes().

What is the CVS revision of sdwindow.cxx of the above code snippet?
In the current 1.35 revision the code looks a little different and
contains comments that may help you to understand it.
