Any idea why this javascript always brings the console up?

Question

I'm not a great java expert but for some reason the code below always brings the console up before it executes correctly.
Any help or suggestions would be appreciated.
Thanks
Steve
// Set Doc Info
// Save existing settings
var temp = this.info.title;
//Show dialog box
var cRtn = app.response("Current Doc Summary is: \"" + temp + "\"");
//Check for empty response
if ((cRtn == null) || (cRtn == ""))
this.info.title = temp;
else
this.info.title = cRtn;
//Set author
this.info.author = "Steve";
//Set Subject if empty
if (this.info.subject == "")
this.info.subject = "Steve Subject"

I just did the same test and pasted the code into a button on a blank form and it executed properly without opening the console too!!
Why it feels the need to open the console when run from a batch sequence beats me, thought it might have been one of the settings to display errors etc but even when they are all de-activated up pops the console each time.
A simple one liner does not open the console so I thought maybe it was a code error that I was missing.
Doh!
