    Ok, got a solution:

    When I want to calibrate my screen in a correct way, then i have to put my stylus a little bit higher and a bit to the right side from the middle of the second cross in the calibration utility...

    Hmm...

    I donīt think itīs realy ok, so what would you do? Is it important to calibrate in a correct way? Will it get even worse someday?

    That is worrying as someone who is getting a 810 soon. You are saying that the default OS on the 810 doesn't work properly with the screen? So they have broken what worked on the previous 800 and 770 (and every previous touchsceen device)?
    And also that it can't be fixed without upgrading to a currently non-available operating system?

    I wish I knew this before I ordered my 810, as I wouldn't have got it.

    No, that is not acceptable. I would return something that did that as not fit for purpose. I wouldn't accept that defect on an expensive device (well, I wouldn't accept it on a cheap device either).

    It's nowhere near as bad as you seem to think it is.

    Diablo is maybe a month or two away, so I don't really see the issue.

    It's not nearly as bad as you seem to think and Diablo is only a month or two away.

    No point in losing your head over a minor bug.

    If as you suggested, the software prevents the touch screen from functioning (ie, making it hard to select something on the screen), how is that not bad?

    Maybe, but Diablo being a month or two away is not a release schedule, it is a guess on your part.

    Yes, got that the first time thanks!

    you didn't describe it as a minor bug. It is registering a position on the screen, not rocket science.

    Tabletrat, really it's not a big deal. There's been maybe three times in total where I've pressed a button on the keyboard and another key was selected. The wrong key wasn't even entered, it was more of a "mouseover" event. I thought I was the only one with this problem but apparently not. But hey, life still goes on. In the three or four times that this has happened in the past month I've had my n800, I wouldn't call it a critical bug. It seems the original poster is having more than software issues though. It's probably a hardware bug if it happens that often.

    But that's just it, it doesn't make it difficult to select stuff on screen.

    No, that's the release schedule . . . "Q2 2008"

    Have you ever programmed a touchscreen driver?

    ok, I got the impression that it did from the post. If not, fair enough.

    Ah yes. The release schedule. They are never wrong!

    Yes, several times going back quite a long way. I have always had an interest in touchscreens, and drivers are not always available, or at least were less common until this century.

    Sometimes when I turn my n810 on, the touch screen is spot on, and sometimes it's very unresponsive (basically unusable) and doing a calibration only gives me ~30 seconds of use before it's off again.

    I'm willing to wait for a software fix, but I'm worried it might be better to exchange it for a new one while I still can. Are these screen problems really common or just on some units with troublesome screens?

    Thanks

    I'm having this problem on my 770. I've had it for over a year, and it just started doing it today. It only happens in the lower-right quadrant of the screen though. When I run the screen calibration tool in control panel, I'm able to tap targets 1 and 2, but on 3 it tells me to tap closer to the center of the target even though I'm dead on.

    I tried removing the battery for 30 seconds and replacing it. Then I flashed the device with the most recent OS2006, but the problem persists. Any ideas?
