When I export a map in flash, hyperlinks do not work. I can see the URL but nothing happens when clicking on them.
this bug has been solved and checked in into the git-repository of FreeMind, where you can find it at
The solution will appear with the next release but is not neccessary published yet.
Another thing is, that you have to publish the flash file on a web server to use the hyperlinks. If the files are locally stored on your disks, flash security prevents the opening of links.
