Spring RTS Engine

does anybody else have this problem? My game sometimes just freezes, i can only ctrl-alt-del to windows and then sometimes can get back to game after waiting a few seconds. this can happen muliple times in a game, sometimes that bad that its unplayable for me, sometimes it goes away...

does it happen when you press alt-shift or ctrl-shift? if so, try disabling keyboard layout switching.

i'm not sure it its caused by that, but i disabled it now, so perhaps it works. thanks for your help
