[Users] {SpamScore: ssss} GeoExt breaks OpenLayers Heatmap

[julia paredes]

I tried Firefox, ie 9 , safari , and chrome, and I get the same result in all of them.I added a single point using the heatmap script and without adding the ext-base.js and I get the right gradients of colours, from blue to red. But as soon as I add the ext-base.js the points are shown in black
