Dear Thierry Zoller,

What URL is is defined by RFC 1738, what mailto: is is defined by RFC
2368. String in question is definetly _not_ URL because of %xx and ".
Double quote is URL delimiter and is not a part of URL, in this case
application incorrectly parses and highlights URL (it should stop before
"). %xx is invalid character encoding. And altogether it's, for sure,
not mailto: URL. Passing unchecked user input to function called
ShellExecute(), where URL is expected, is a bug.

So, while there is a security vulnerability in Windows, there is also
security vulnerability in mIRC, Acrobat Reader, Netscape, Miranda,
Skype, because ShellExecute() behaviour is not defined for the case
non-URL data is passed to URL processor.
