no worries at all!!!! i took a look and actually all of the 4:3 resolutions work fine, it appears this issue is only with the 2560x1440 option which is the only one that launches in 16:9.
ah, thanks for checking! as you can probably tell it wasn't developed with widescreen in mind, haha. i'm looking at putting together a fix for the mac command line issue and will hopefully be able to turn off that 16:9 option for new builds, just as i think it's caused some issues and it's something i can't test myself!
