integer alt = peek4s(event+8) integer control = peek4s(event+13) integer shift = peek4s(event+16)
I have to say that I would be quite surprised if that should not be
integer alt = peek4s(event+8) integer control = peek4s(event+12) integer shift = peek4s(event+16)
I did test with changing the +13 part to +12 and I still got the routine bad number error after I changed them to integer values just for testing purposes. I had to change them back to atom types for it to work again.
No, Pete's right. sfBool is typedef'd as an int so the offsets should all be four-byte aligned.

This is why I always recommend planning out structs with constant instead of using magic numbers.

Thanks for the tips. I'll keep this in mind.
