Security issues

It isn't, but this could be a Trojan horse, like any program, you have to trust me.
As to viruses: Macintosh users need not be concerned, there are none for that platform at this time. For Windows, I can state that I personally compiled this progam (using Flash CS4 on a Mac) with no malicious code intrusion and placed it on this site.
