OK, well, I still get the effect when I first switch on the player.

There is a known bug in the 2.0 beta 11 player software, where the all inputs behave in a very sluggish way immediately after boot time. This appears to be unrelated to Hijack. If you're having problems with a macro not responding properly at boot time, then it's likely that when this bug is fixed, your macro will start working again.
