I experienced no problems with the installed firmware (versjon 14) with my X10, but I read on a forum that some people had gotten their device a bit faster and smoother after installing the update that is available (version 16). I installed the update and now I regret and wish I never would have done it. Now I have the problem with the "a" butten. When I hit the "a" button, I just get that the button was pushed and nothing happens in the textfield, so I have to push the "a" button twice to get something. I couldn't find my wireless internett that was turned on, and in some of the programs when I write, nothing shows up in the textfield, but I can see that the text registered by the device because I can see the wordexamples coming up as I write. This is very enoying as you can see, so I wonder if there is a way to downgrade to the preinstalled firmware?
