I experimented with this for a while. It is difficult to get working and nearly impossible to get working every time. In other words, when you stick your finger to slide things, you never know if it is going to work or not, pretty much as if you were pressing a button without jitter removal.
(please, don't take this in a rude way, actually I'm really calm, and trying to explain our side also ok? )

Well, you need to understand my position we are trying to follow an idea, and this must have no arrows / select area. Of course we are not good still, and the screen doesn't help, but there's several users that have no problem with that, others that have a small problems (small error rates) and others like you that have more problems.

But I will not change Canola's main design principles based on the smaller number of users. Unfortunately not. We tried (doing the taskbar) but just do not work for us.

There's other ways, and I think pycage has done the way people expect and also Kagu : you need to touch a play area to do stuff, so scrolling is always safe. So I can only point you towards them, because we will not implement those ideas any time. Actually I think it will be easier to maemo to have a capacitive / precise screen faster than this ))

You may want to change the way you register a click and introduce a "jitter protection" of a sort. For example, you may want to register a click only if there is no movement 500ms past the UP event.
Well, you're not the first one to come with "numbers" and believe me: we have tested so much so much combinations, and also there's threshold for movements, click, everything. The thing is : I really think even when you are moving your finger : you are not generating events, or your screen has some problem of some sort (interrupted events - but I don't believe that)

Your last quote actually tells me something :

PS: BTW, I have never been able to invoke Nokia's on-screen finger keyboard. I am always getting a stylus keyboard, even when touching screen with a finger. This may somehow be related to Canola problem described above.
This means 2 things : one ) you have a problematic screen, failures in the pressure part because , the thumb only comes when you press with a finger (several touch points) and with some pressure. If you don't get it, by pressing with your thumb I suggest you to try other device and see if the same happens. two ) you have a personal way of touching that makes the simple click happens to fast, and with concentrated pressure, thus "being" registered just like a stylus.

But in the end, as you said that with the stylus also failed, I really think that can also be the problem on the screen : / (not removing the blame from us, I know we are far from being good on this, but you just seems to have more problems than the average)

Can you find another device with a friend to test this? and pass your device to your friend to see if the same thing happens with them ?
