TestComplete How to exit immediately if object not found, rather than waiting for autowait to finish

How about this:

function verifyBrowserScriptErrorWindowAppears()
{
// Verifying an unexpected script error window is appearing before operation and if yes then closing it.
if(Aliases.xmetal.BrowserScriptErrorWindow.WaitProperty("Exists", true, 0))
{
Log.Message("Browser Script error window appeared.. Closing it..");
Aliases.xmetal.BrowserScriptErrorWindow.Close();
}
}
