SJSRO Resolution

Is there a chance to change Resolution of SJSRO to 1920x1280 ?
Because all my other windows etc will be changed in resolution too if i play sjsro.

Thank you!

no, just the 3 that are in game:P
or just use windows mode

copying my text from srokey
you cant because the client is too old for it.
you can play it in windowed mode if you press Alt and hit enter

hm.. shit =/
