<br>
2) The pinch handler now stops the browser default behavior on handled touch move events. This may stop the page drag on older iOS.<br>

I'm still unclear about whether the undesired page dragging only occurs in the sandbox example, or whether you also see it on the trunk.<br></blockquote><div>Ok in you sandbox (<a href="http://dev.openlayers.org/sandbox/tschaub/click/examples/mobile.html" target="_blank">http://dev.openlayers.org/sandbox/tschaub/click/examples/mobile.html</a>) and not ok in the current trunk. <br>

Thanks for the testing & feedback.<br>

Hi Tim,<div><br>
It's really a great function, and so fast !!!<br>
I put two answers inline,<br>

Hi Tim,<br>
<br>
Thanks for these improvements. I have tested on several<br>
plattforms (see<br>

I face the same issues like Steven. In addition, I have observed the<br>
following things:<br>
- iTouch 3.1.3: Pinch Zoom Dragging -> it moves the browser<br>
instead of<br>
the map and makes the function ineffective<br>
<br>
<br>
I also saw the same on an iTouch before upgrading. But I'm pretty<br>
sure I saw it on the trunk (instead of just on this sandbox). Are<br>
you seeing the issue in this sandbox and not on the trunk? (I've<br>
only got access to an upgraded iTouch, and pinch zooming works there.)<br>
<br>
<br>
I have tested on your sandbox: Here is a small video that presents the<br>
issue:<br>
<a href="http://www.youtube.com/watch?v=6VoVKeOy9dg&feature=player_embedded" target="_blank">http://www.youtube.com/watch?v=6VoVKeOy9dg&feature=player_embedded</a><br>
<<a href="http://www.youtube.com/watch?v=6VoVKeOy9dg&feature=player_embedded" target="_blank">http://www.youtube.com/watch?v=6VoVKeOy9dg&feature=player_embedded</a>><br>
(sorry for the quality, but I'm not Spielberg). I can observe that the<br>
pinch function is working, but the browser window moves. I don't observe<br>
that on the iPad 4.2. If it's an iOS version issue, I don't think it's<br>
so important.<br>
<br>
<br>
<br>
- Android Nexus S: the double click seems to work a bit better,<br>
but has<br>
still issues. No idea why (but this is a very empirical observation)<br>
<br>
<br>
Sounds like the 10 pixel tolerance for double clicks may not be enough.<br>
<br>
I'd be curious what you see for pixel displacement on typical<br>
double-tap sequences (on a touch device).<br>

<br>
<br>
I have added an average and standard deviation function:<br>
<a href="http://dev.openlayers.org/sandbox/cmoullet/openlayers/examples/dpx.html" target="_blank">http://dev.openlayers.org/sandbox/cmoullet/openlayers/examples/dpx.html</a><br>
<br>
iTouch 3.1.3: pair: 30 - avg: 4.2 - std: 3.1<br>
iPad 4.2: pair 30 - avg 6.7 - std: 2.5<br>
Android Nexus S: pair 30 - avg: 8.3 - std: 4.5<br>
<br>
These are of course very empirical results, but it seems that I'm less<br>
precise on an Android nexus S. So the tolerance should be a bit bigger.<br>
