AssetsModule.ResourceMinimizer JavaScript compression problems for resource 'SuperfishStack' JavaScript stack...

Hi,

I'm seeing this on my production server, but I've not seen this during development. Everything seems to work ok though?

IS there a version I need to update or some kind of tweak I need?

John
