The behaviour you are describing was a known issue of MapBuilder 1.5alpha1 on Internet Explorer, and it has since been fixed. MapBuilder 1.5rc1 does not have this problem any more. So I suggest that you upgrade your MapBuilder installation. > I added more functions like transparent gif acetate layers on top of the > base map.

Also, the available cache size is determined by your browser cache settings. Firefox 2 is known to need much memory for cacheing images, but Firefox 3 will not any more. If you do not want to have images cached, you can use "WMS" instead of "WMS-C" as layer type. Also, if you have many layers, it might make sense to get them from the server in one piece (e.g. if it is just background data). You can have a comma-separated list of layer names in the layer's <Name> properties in the context xml.
