Buttons do unexpected Things

[Drseuss]

I had a look around the forums but could not find anyone else with these issues.

Basically I have attached a usb controller to my computer. I configured project 64 for this controller and I load a rom. however, once in the rom, certain buttons do unexpected things: the start button (plus), for example, toggles the emulator between windowed and fullscreen mode, while still working as the start button in-game. Also, my select button (minus) locks and unlocks the mouse. this isn't an issue because the select button isn't bound to anything, but I don't remember having bound these buttons as shortcuts to do these things. Can I change the shortcuts? Where would I do such a thing? Thanks...
