keyboard problem with 2.10

i just installed zc 2.10 but now the game doesnt work wel with my keybourd.
these are the problems if i press my left alt(the a button)it think's i pressed the windows button.
and if i press left ctrl(the b button)it think's i pressed scroll lock. 😕
with 1.92 the game did'nt have this problem.
and now i can't play a single qeust not even the standard qeust becouse i cant attack a single baddy. 😞
so how do i solve this irritating problem.
