Strange keyboard problem, only in Adobe After Effects

Hi,
I have a brand new laptop with Windows 8.1 and a numeric keypad included with the keyboard. The keyboard has Norwegian keys. I have a problem that's driving me crazy, and I have been to several other forums and talked to hardware support for my laptop and software support (Adobe and Microsoft). Nobody so far has a clue how to fix this:
The HOME and END keys are used a lot in Adobe After Effects.. by themselves or with modifier keys ( shift, ctrl, alt, etc.)
I have the following two methods on my keyboard for HOME and END:

Method 1. Use the Fn modifier key, and press one of two keys labeled "PgUp/Home" and "PgDn/End". This does work in AE (and every other program), but it's less than ideal to use the Fn key.. epecially since there are other shortcuts in AE where other modifying keys are used in combo with HOME and END.

Method 2. Turn Num-Lk off, and use the 7 and the 1 on the numeric keypad. (In addition to being labeled 7 and 1, they are also labeled HOME and END). These keys would be my choice to use, but they don't work in Adobe After Effects. The strange thing is that they work in all other programs, including other Adobe programs like Premiere Pro!! It seems like these keys work everywhere EXCEPT in After Effects. I have tried Num-lock off (and on), and switched the input language between US English and Norwegian. I have already been in contact with Adobe about this several times, and I have an open case with them. Several techs there have been scratching their heads, not able to figure out what the problem is. The latest thing I tried with Adobe while troubleshooting was to try with the onscreen keyboard. The HOME and END keys work just fine there. I would also like to add that I have worked on several PCs with English and Norwegian keyboards, and never experienced anything like this before. HOME and END have always worked in Adobe After Effects.
Any ideas why this is happening and how to fix it?
