I don't believe Hijack has anything to do with it. This is Beta7.

Behavior seems to be:

When in the main "first entry" screen of the equalizer (where the preset name is at the top), the number keys select the presets.

When you are in the mode of selecting individual bands, the number keys 1-9 jump to equalizer bands 1-9. The 0 key is a quick shortcut for zeroing out the value of a given equalizer band (so you can't jump to band number 10).

Does that seem to coincide with your observed behavior?
