gmap markers dissapear in Internet Explorer

I'm using the hierarchical_select module, which is using jquery interface and noticed that when the jquery interface module is activated all markers dissapear on my Google map (gmap module) view when using Internet Explorer (6 and 7). In Firefox the are still there.

I suppose it is probably rather a bug in IE than in the module, or in the fact that IE, Google maps and Jquery interface maybe don't work together.

My Google map has its own php template so I removed the jquery_interface.js link there manually from the html (I only need it on node add pages), but I feel it's a bit hacky solution.
