[Plugin: Comprehensive Google Map Plugin] Transparent DIV

Hi there,
I’ve installed the plugin and it works fine. There is just one problem: there is a transparent div above the map that doesn’t allow me to use the map controls (like: drag, zoom, view street, etc). I’ve been trying to fix this, but I couldn’t find the div on the code. Could you help me, please?
Thanks in advance.
