<font face="Century Gothic">I am having a weird problem and have tried
almost everything to fix it.<br>
<br>
I am creating a bunch of GML files and pointing them at open layers to
draw lines over a map. The lines are being drawn Ok but when you pan
up, the location the lines are on the map does not move the same amount
as the map. Also the lines at the top and bottom of the map do not
follow the roads that the location references give (where as the ones
in the middle do).<br>
<br>
This problem seems only to relate to the vertical axis, not the
horizontal.<br>
<br>
I have stripped back the code to the most basic components and it has
made no difference and am referencing the on line version of open
layers. I have also added the google workaround.<br>
<br>
Any help appreciated. <br>
