I haven't had that problem with the power button. I have had problems with power-on macros involving other devices, where the remote would freeze for several seconds before actually trying to perform the action (and failing to then, I think). One thing that you may not have noticed yet in progamming the 2100 that I believe was part of my problem (horrid manual, by the way) -- when you are teaching it a button, it says to hold down the button and wait for the beep, but what it doesn't mention is that you should actually tap the button briefly and wait for the beep. If you hold it down the whole time (which I did for a bunch of buttons for my digital cable box before I got around to teaching it the 1050), a single brief press of the programmed key on the 2100 will transmit for several seconds because that's what it was taught.

I've also had some trouble with teaching it macros, but haven't really taken the time to track down the problem (I've got a "power on" macro working finally for the 1050, digital cable, and TV, but the "power off" macro fails miserably, I think because of some timing problems on the 2100's part). Hope that helps you some -- it's a nice remote, but definitely has some quirks.
