With Downlaod Express you are able to stop it functioning temporarily by holding down the `shift` key while clicking on the link.
What I was wondering is if there is an option to temporarily turn off Download Express for a period of time, and then an option to re-enable it.
Thank you for writing us.
Yes, this is possible.
Please open the Download Express Options dialog, Integration page. Please check the "Monitor clicks with hotkey only" box and click the OK button.
Download Express will not monitor your regular clicks, but you can send any link to Download Express by depressing the hotkey combination (you can change it at the same page in Options) and clicking the link.
