Hmm... I don't understand.. As I have explained [1], my builds are done 
from scratch in a clean tree, so I think I am not switching from a 
"non-horizontal scrollbar build to a horizontal scrollbar build".

For example, with rev. 117599 (MSYS2/MinGW64 build) and with only this 
file in %APPDAT%/.emacs.d,

$ cat %APPDAT%/.emacs.d/init.el
;; Instead to save in ~/.emacs.desktop
(setq desktop-base-file-name "~/.emacs.d/desktop")

;; Instead to save in ~/.emacs.desktop.lock
(setq desktop-base-lock-name "~/.emacs.d/desktop.lock")

;; Save desktop
(desktop-save-mode t)


the following occurs.

Start Emacs with the link created by addpm (i.e. pointing to runemacs). 
The frame shows the scratch buffer and both scrolling bars (HSB and VSB) 
are visible.

Now visit a file, for example init.el itself: C-x C-f .../init.el

Now close Emacs (click on the 'X' icon on the top-right angle). Emacs 
asks to save desktop. YES

Now restart Emacs with the same link. Emacs opens showing init.el file 
but with only the vertical scroll bar (VSB).

Now switch to previous buffer with mouse-1: the scratch buffer is 
visible with both the HSB and VSB.

Now switch to the next buffer with mouse-3. init.el is visible with both 
scrolling bar.

So, only when one starts Emacs, the buffer active (that on which the 
user was working in the previous session before it is closed) does not 
show the HSB. Just switch to another buffer and also the first acquires 
the HSB.

If it is a bug I will report it to bug list.

Ciao,
  Angelo.
