Mousepointer freezes / wlan gets disconnected

[MrBeanistderbeste]

hello. i have an annoying problem when playing the nightly with the version 203. i play in window mode and 3 times in a row i had big freezes when moving the mouse on the map. its not only in settlers on my desktop too. then my wlan gets a disconnect too and because my mouse freezes i cant even click anything. its really annoying because if we play with many player the host always has to reopen the game and i get a rage xD i hope someone know what can be the problem ^^
