[as2 & CS4]Help needed

Hello,

I am currently working on a project for a client that requires a stand alone application.
I am using Flash CS4 and AS2 to achieve this. The application is quite simple and truly I should be done but I am having an issue with the ‘getURL’ function.

On the main screen of this application I have two buttons.

This is the following code I used:

link1.onRelease = function(){
         getURL("http://www.website.com/default.aspx?utm_source=VisitWebsiteLink&utm_medium=InstructionalCD&utm_campaign=ShopInProPhase2-080709");
      } 

The issue I am having is this. When the button is clicked it opens a browser window and actually goes to the right page, as it should. BUT, the above URL is getting cutoff in the browser window, displaying this:

http://www.website.com/default.aspx?utm_source=VisitWebsiteLink&utm_medium

My client is saying that the entire url needs to be there or the tracking for this app to their site will not work. I don’t know if it’s dot displaying or actually not going to the requested URL. I have searched High and low for a solution and I am about to pull my hair out. Is there a limit to the length of the URL? I know browsers have limits, but this URL isn’t really all that long so I am confused. I have tested this out as a .swf and a .exe with the same results.

Thanks in advance
Chris
