Weird bug

Why is this not working?


if (Key.isDown(49))        // 1
            {
            if (Key.isDown(17))                    // control
                {
                }
            }

And why is this actually… working?


if (Key.isDown(53))        // 5
            {
            if (Key.isDown(17))                    // control
                {
                }
            }

They’re both practical the same as you can see but one is working and the other isn’t, wtf?

Thx
