How to reproduce:

1. Download two ADOM R59 windows versions: with and without NotEye.
2. You may clear adom_dat directory, it doesn't plays any role.
3. Run version with NotEye and exit it.
4. Run version without NotEye and exit it.
5. Run version with NotEye again.

Actual result:
adom.kbd file is overwritten on steps [4] and [5].

Expected result:
adom.kbd shouldn't be overwritten on these steps.

And please don't say that it might be intended or that both versions aren't supposed to be played from one PC. And don't tell that most players will use only one version - I like both of them and which one I would use depends on my mood :)
