Just to follow on from the previous topic: Using AFC Flash Mapping Components:
I made some time to check out AFCs UMap component. The Flash actionscript is different because it is based on AS3. The result is pretty similar to what I had with GMap. I have not worked out a way to link to Google Maps yet - there seems to be a work around but I am not there yet. Instead UMap still defaults to Microsoft Virtual Earth tiles.
What I had not reliezed was that there are two implementations of UMap - UMapper.com is an on-line HTML version and the other (UMap AS3) is a Adobe Flash integrated component. Once you have placed a marker on your map in UMapper you can either link to it using an html link (like Google Maps) or you can copy the Flash AS code and insert it into your own Flash project.
It is all free for you to try out. Commercial licenses cost extra.
