Hi Sean,<br><br>At the moment I haven't tried to address this issue so I'm afraid I won't be able to help you.<br>Notice
that the problem occurs if you try to use more than one vector layer,
but there won't be any problem if you use one vector layer and several
other layers.<br>
<br>Let me know if you give it a try!<br><br>Regards,<br><br>Jonathan<br><br><div class="gmail_quote">2009/12/10 Sean Gillies <span dir="ltr"><<a href="mailto:sean.gillies@gmail.com">sean.gillies@gmail.com</a>></span><br>

<br>
I'm intrigued by your svgweb renderer. It looks useful to me in a<br>
project where I already possess nicely styled non-geographic layers of<br>
lines and text annotations as SVG, but don't want to reinvent the<br>
background image layer machinery and navigation and layer switching<br>
controls provided by OpenLayers.<br>
<br>
As you state in the table, multiple layers aren't working with flash<br>
forced. What's the problem with multiple layers?<br>
<br>
Regards,<br>
Sean<br>
