<p class=MsoNormal>Hello,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’ve recently updated one of our applications to
OpenLayers 2.7. Previously we were using an OpenLayer.js file with
revision 2106, which appears to have been somewhere between 2.3 rc2 and
rc3. Now when I plot vector features on a vector layer I am seeing
strange behavior in IE6 that did not happen before. When I pan the map
the vectors follow, but as soon as I release the mouse they do a small jump in
the direction that I panned. So for example, I drag the map so that I can
see further East and as soon as I release my mouse button the vector images
jump a few pixels to the East instead of staying at the correct location.
This also happens when using the navigation arrows that are at the top left of
the map. I’ve tested this on the OpenLayers example site (<a
href="http://www.openlayers.org/dev/examples">www.openlayers.org/dev/examples</a>)
and I am seeing the same behavior with vectors and markers. This only
affects IE6 though, FF2, FF3, and IE7 seem fine. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>So I’m curious if there is a workaround for this,
other than removing all of the vectors and replotting them if I detect a drag
event. Is there some function that I can call that will fix vector
positions? I’ve tried attaching to the ‘moveend’ events
on both map and layer to call layer.refresh() and layer.redraw() but this doesn’t
seem to help, and I’m not sure but maybe these are already called on a
move anyway. Any other suggestions?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks,<o:p></o:p></p>
