So here's a new one! I have an Alps64 board which used to work (as far as I remember), but I put it away because I needed one fewer keyboard than previously. Now that I've picked it back up, it has this kind of odd problem:
It starts out in layer 1 instead of 0! If I have FN keys available in layer1, they work fine, so I can access layer 2 and so on, and probably even layer 0, though I haven't tried making a new keymap just to test that.
So now I'm really confused. I've tried plain.c from TMK and my own keymap, and both start up in layer1.
I supposed I can just push all layers up one number and see if that works, but this is still really weird!!!
