SSGetStr() uses its own static keypacket. Thus, if you use a modifier key (Ctrl, Meta, Super) to use a function that calls SSGetStr(), the key release signal of that modifier key will not be known to ssatori_main()'s keypacket variable, and instead will be registered to SSGetStr()'s keypacket. As a result, your modifier key flag will not be cleared, and you have to press that key a second time to send the release signal.
1 solution I initially used was making SSGetStr takes a keypacket pointer. However it doesn't make sense that a function to log out have to take a *keypacket parameter.
Using global variable might work, however most programmers are against it.
Let me know what solution you thought of, and possible try to re-implement SSGetStr()

we need RGB keyboard driver for rainbow glowing the dark keyboard. trust me this is mandatory and crucial for the development of this OS.
