Hi All,
Yesterday I found that the mouse-stick and both mouse buttons on my R2H had stopped working. (the touch-screen still worked though) I re-installed the drivers for the synaptics pointing device, but that did not solve the problem. Rebooting didn't either.
Then I tried to remove the battery to see if that helped. And it did! Just posting this because I think this information might be helpful for others...
Cheers! Stefan.
