MAME and mouse button B1

[+Swami]

When I use the mouse as a controller in MAME for two-button games, the right mouse button, B1, (as opposed to L mouse button B0) often toggles me into the desktop or Display Settings, minimizing the MAME window. Is there a way I can stop this from happening in the MAME settings?

 

thanks

Hm, strange. Have you controlled in the input-settings of STELLA, if you maybe have the mousebutton also mapped accidentally to another thing in UI-Events or Emulator-Events?

Is the problem game specific or does it happen with all games that use the mouse?

What version of mame? What's the operating system? What's the mouse? Do you have "offscreen_reload" enabled? Upload your mame.ini
