I have a reporting engine that works off of tomcat. This applet is then introduced in an iframe into a regular html page. When a person clicks on the View Report icon, a div then appears that says Processing. On one instance, when a user selects pdf, the div disappears as it should because they are forwarded to the next page. But whenever the user selects .xsl or .csv, then a popup appears to download a file. Unfortunately, the div layer does not disappear when this popup appears, nor when the user presses okay or cancel. Is there an event listener I can tie to this popup window for file download? That if a user presses okay or cancel that this div layer should then hide?
