I was playing around with the control panel and now the touch screen does not work anymore. The key at the right top that normally enables/disables the touch screen does not fix this. Even when it says the screen is unlocked, the touch screen seems to be locked.

Has anyone run into this problem? How do I fix it?

Nokia N810

I figured it out. For those who have this issue -
1. press the on/off button for a short time - a menu wll show up
2. switch off from this menu
3. power on again by pressing the on/off key for a long time
Everything is back to normal

duh????????????????????????
