I'm talking about the four buttons across the bottom of the screen when in portrait mode. These can be long pressed for other options. For instance the home button when long pressed presents a program switcher screen (which has gotten awful for me since the 2.0.1 update... never has Gmail or browser which are the two most common ones I need to switch to) and the Search button also gives some other options. I noticed a while back that sometimes my home button wouldn't respond to a long press. I would get the initial vibrate from the single press but it wouldn't register the long press with a 2nd vibrate and bringing up the program changing screen. This is quite frustrating as it then takes several key presses to get to the program I'm trying to change to. I also recently installed an app called jkAppSwitch which works like the long press home key program switcher with more customization. Since the standard switcher no longer shows my browser or Gmail I figured this was a better solution since the other wasn't adjustable. For the first day or so this worked perfectly, long press on search and then there were all of my open programs. Then, recently, it quit working entirely just like the Home button had done for long presses. Short presses still work and long presses give a short press result however no long press. I tried power cycles to no avail. This is quite frustrating and if the stock changer were to work the way it had when I first got the phone I wouldn't have the 2nd problem but it does not and so I'm left with two problems to the same issue.
