Andy McFadden 9c5ba9ca4b Work around the mysterious shrinking side-window problem 
When a project is opened, the main window layout subtly changes.
Of particular note: the vertical splitters below the references and
symbols windows shift upward 1 pixel when a project is opened, and
back down a pixel when the project is closed.  So if you close the
app while a project is open, the settings file gets updated with the
new values for the sliders.  If you restart the app a lot the effect
becomes noticeably fairly quickly.

I'm not yet sure what's causing this.  I'm currently working around
the issue by not updating the window sizes in the settings file if
they're off by only one pixel.
