IE and zooming out

[GoogleCodeExporter]

What steps will reproduce the problem?
0. only in IE ( FF, Chrome works fine)
1. zoom in
2. put markers ~1000
3. try to zoom out

What is the expected output? What do you see instead?
IE hangs up and says: "A script on this page is causing IE to run 
slowly....."

What version of the product are you using? On what operating system?
XP, VISTA, markerclusterer 1.0

Please provide any additional information below.

In FF and Chrome everything works fine, the problem comes up only in IE (7 
and 8 too). When you load the example page, zoom out, refresh the map via 
the button "Refresh Map", and then zoom in it works fine. But in the 
opposite direction, namely when first zooming in to the level where there 
are no clusters only the individual markers, than refresh the map via the 
same button, then trying to zoom out, it a kind of hangs up for a while and 
IE says: "A script on this page is causing IE to run slowly....."
