Can someone please verify the following observation?

On a Windows 9X system with an MS mouse that has a wheel (between the two 
buttons), I see a strange phenomenon.  When a DJGPP program (Emacs in 
this case) initializes the mouse driver, the returned info says that the
mouse has 3 buttons.  However, only 2 of them (the real buttons) are 
visible to the program; clicking or turning the wheel doesn't get reported
to the DJGPP program.  (The wheel does work with Windows programs, so it 
is not a hardware problem.)

I knew that the wheel is inaccessible to DOS programs, but what surprises 
me (and Emacs!) is that the mouse does pretend to have 3 buttons 
nonetheless.  The problem with Emacs is that it thinks that the right 
button is mouse-3, and mouse-2 is absent.

I wonder whether this is something peculiar to my system or a general
misfeature of this type of mouse.

Thanks in advance.
