I'm making a game which will be compatible with computers using multiple screens (like mine)

What would the best way to do this? I'll be using different windows in the interface depending on if a player is using multiple screens or not.

BYOND doesn't handle multiple monitors at all well.

Basically, you are walking into both uncharted and bug-ridden territory.
Multimonitor setups and BYOND just... don't cooperate. There's so many workarounds and jerry-rigging that needs to be done to do it.
