[OpenLayers-Users] Internet Explorer doesn't refresh vector layer

[Michael]

I have found that, in many instances, the order that scripts or 
functions are invoked can be very sensitive in IE.

This can affect variable scope, as well as whether an object or value is 
properly passed to a function or object such as an ajax call.

Try starting your ajax cycle much later in your timeline.  I put mine at 
the bottom of the page in a separate little block of script.

Best of luck

Michael
