Not sure if anyone else has cone across this. I'm 4 Boxing with no problems. (except when I die. Then it's the fault of the softwAre/hardware/dog)

when I try to create a 5th window in maximiser, it comes up as green instead of blue and doesn't launch at all through the command line. Is there something I've missed? I've been running Outland instances with 4 but would prefer a 5th frankly. I'll try and post a screenshot later this week if this is not common.

Specs:

Cheers!
