[OpenLayers-Users] IE8 problem with VMS

[Enrico Sartorello]

I'm rendering something like 30-40 features, all squares filled with a
color.

I don't think it's a problem of resources because if I use "EmulateIE7" the
layer is displayed quite smoothly (but I have some other compatibility
issues), and also with the other browsers I don't have problems at all.
