[OpenLayers-Users] approach to memory leaks in IE

[Wolfgang Gehner]

Hello,

I have started to use OpenLayers (with IE7 on Vista) and am finding
that a webapp that navigates to an OL.map gets slower over time (seen
in initial load time as well as in the speed of rendering polygons,
for example).

So I started to dig into memory leaks, with Drip
(http://outofhanwell.com/ieleak), beginning with some very basic
examples.

I am finding that every screen refresh increases browser memory
consumption by a few MB. I saw this on

http://openlayers.org/dev/examples/stylemap.html but also
http://openlayers.org/dev/examples/accessible.html
http://openlayers.org/dev/examples/all-overlays.html
http://openlayers.org/dev/examples/baseLayers.html

What's the recommended approach to deal with that?

Warm regards,

Wolfgang
