Removing auto text in app.alert window title bar



I added the following JS to a button and it works perfectly. Almost! I'm still getting the automatic text "Warning: JavaScript Window-" showing in the title bar. Is there a way to clear this and only show my custom text?

app.alert ("List specific services and service levels that are legislated (reference applicable legislation).\n\n" + "For example, one long term care bed in rented facility.", 3, 0, "Legislated Mandatory Service Requirements");
