After having similar problems in other games I have done googling and some searching and asking questions etc. And I have found a fix!!!How to fix the problem with keyboard controlls messing up.For some reason multiple games have this problem with Infra Red Devices and for some very strange reason it messes with your keyboard settings.To fix in Windows - 1) Click start2) Click Control Pannel3) Click Device Manager4) Expand the Universal Serial Bus Controllers tab. (USB to you and me ;) )5) Uninstall the Microsoft eHome remote/receiver or Microsoft eHome Infared Transceiver or similar driver.6) Restart the game and it should be good.This is the way I have fixed multiple problems with many games including Fallout 3 and now Blockland, I hope it works for anyone else having the problem.
