Mark,

No comments about the current MESS source code but a few on MESS.

The latest version I'm running is MESS 1.58. Even though the configuration menu 
states there is only Button1, you can see two entries, for ex. RIGHT BUTTON1 
which have different keys.
With MESS using my PC joystick, there are clearly different responses to the 
right/left joystick buttons. The Right button will switch between OS-9 windows. 
The Left is active for selecting items in MultiVue.

So the source code is wrong but it is cosmetic not functional.
