I just found a bug in Googlemaps' Flash component.
BUG: When a mask is used over the map component, the copyright and MapTypeControls Fonts (possibly other control fonts) are hidden. The buttons still work.
Originally, the map itself didn't have a mask, but was imported into a wrapper banner ad that had the mask - same issue. It took a while to isolate what the issue was. Hope this helps someone out. I'm posting images to showcase it_

Instead of using timeline, just use actionscript_
map.mask = mapMask;
