I just downloaded and installed Build 1970 on my MacBook Pro and I'm still having an issue with the numeric keypad Enter key - it is still sending the AltGr code. I'm using the MacBook with an external Apple keyboard. I own a personal license of Parallels for my iMac at home and it now works properly - build 1966 fixed the keypad enter there. However, my work machine is the Macbook Pro and build 1966 and 1970 both exhibit the problem. Here's more details that I wrote when 1966 was realeased: I was excited to see that the Enter key behavior was fixed. However, nothing seems to have changed on my machine, I still get the AltGr when I use the numeric keypad Enter key. I've turned the keypad on and off using the clear key with no luck. I also use TradeKeys, a utility that lets me re-map the keyboard to swap the Alt and Windows keys so they match the Mac's Command and Option. I've removed all mapping there and the enter key is still sending the AltGr. (When TradeKeys remapping is running, the Enter key acts as the Windows key -- as expected.) Any ideas on what's going on? Andrew mentioned using a keyboard configuration file to change the Enter key behavior. Have I (or TradeKeys) got something messed up there? Any help on how to troubleshoot would be much appreciated!
