Crash when changing resolution in OpenBOR

As the title says i have a crash when i try to change the video resolution in OpenBOR, in particular when in game i try to set this one:
----
Video settings --> Screens
2X - 960*544
----
 
In general this is not specific as i can reproduce this kind of crash in almost any games that use this kind of resolution, other than that OpenBOR is almost 100% stable :-)
