getURL cgi help ......please

hi all
need some help, i fixed up a feedback form in flash, and all went well, an email message was set to the email i provided in my .cgi script, however a new internet explorer window pops up when i click on the send button, how can i let my form send the information to the script and thats it, without the script opening up anything.
the send button has the following actions:
getURL(“http://mysite.com”, “_blank”, “POST”)
if i remove the _blank the cgi page opens up in the flash movie window

please someone help
waiting…
many thanks
