[OpenLayers-Users] Shifting markers and vectors in IE6 after pan

[Andreas Hocevar]

Hi,

the current version of OpenLayers is 2.8. But you are saying that you
see the same behaviour on the OpenLayers examples site? I just tested
on IE6, and I do not see it (neither in the vector-features.html nof
in the markers.html example).

Can you provide an example where this happens?

Regards,
Andreas.
