[tubikkupilnout]

Hi, need API Frame GetPropagateKeyboardInput alternative for 3.3.5a 12340
It work fine on 7.3.5 but not on 335.

nil value

I got EnableKeyboard(true) but it trash
it blocked out the whole movement etc. you can check the button name. but cannot move and play game

f:EnableKeyboard(true) --or false

local function up(self, key)

end
f:SetScript("OnKeyUp", up);
