Window unshade fails to expand window

Apologies, I may have already reported this.

First set the left double click mouse button action on the title bar to "Shade".
Then double click the left mouse in a title bar.
    Result - the window shades correctly

Double click the mouse in the title bar again to unshade the window
    Result - the window unshades but only by a very small amount, typically to just under the menu bar.

I am using:
