Conflict with GMAP location

First of all, thanks for the excellent module!

I've noticed that in IE, if my page loads both a GMAP and AddThis module, only the GMAP section works correctly - the AddThis button is available, but the dropdown menu doesnt render correctly (its just raw text). Perhaps there is a javascript conflict?

For the record, I can have both modules on the same page in FireFox with no problems. But in IE, they only work when displayed seperately.
