OK.  But you didn't answer my earlier questions:

In a normal frame with tool bar, please evaluate the following
three forms

(tool-bar-height nil t)
(tool-bar-height)
(frame-parameter nil 'tool-bar-lines)

and tell me what they give.  I fail to understand why `tool-bar-lines'
is 2 in your saved desktop.

And while you're there: In a saved desktop find the (tool-bar-lines . 2)
entry, replace it with (tool-bar-lines . 3), fire another instance of
Emacs and tell me whether the frame height decreased.

Please do that now.

Thanks, martin
