[JS] doScript Question

HI.

I have used doScript in the past with success, but this time I am getting an error

"Cannot handle the request because a modal dialog or alert is open" when running from ESTK, and the line: "app.doScript(myOpenScript);" is hightlighted.  From InDesign, nothing happens, not even an error.

here is the bit of code I am using:

myScriptFile = File("~/Making Tickets2.jsx");

myScriptFile.open();

myOpenScript = myScriptFile.read();

myScriptFile.close();

...

if(myButtonFive.value == true)

{

app.doScript(myOpenScript);

}

When I use the console I am told that the string "myOpenScript" is the correct script, The script it is running is a simple alert box.:

alert("Hi");

I have tried passing the file path to the doScript and get the same error.

Any ideas what I am doing wrong?

Cheers

Roy
