Troubling Keys

hello there…
i have my renoise account installed on two different computers (both mine don’t worry :) one is pc and the second is a dell laptop… on the pc everything is fine with renoise but with the laptop i have some problem with command keys…
i cant write commands like e1 near the sample chord , or undo with with ctrl z , cant write anything with letters only numbers for example cant write in volume 7,8,9,10,1A, 1B
the version im using is 2.5 ,
tnx and good day

Maybe its something wacky with the function key
