Progress Indicator stops on File Download popup


I am developing a file download page with an indeterminate mode progress indicator. I have implemented the file download in such a way that , when clicked on the button the ‘Save As’ popup appears. (in IE and Firefox).

Now the problem in case if any ProgressIndicators are running in the page, once the File ‘Save As’ popup appears, all the ProgressIndicators stops. even if u dismiss the File download popup and create a new Progress Indicator, it doesn’t work. It doesn’t work in the sense, the indicator icon shows up but it doesn’t spin.

I have created a sample project to demonstrate this [refer screenshot]
. I have attached it along. it is a 1 page application with 2 Progress indicators and 1 File download button. Its is an eclipse-maven-vaadin project with a jetty server. please extract and run ‘mvn clean install’ followed by ‘mvn jetty:run’. The steps to reproduce are give in the web page and the screen shot

Any help will be very much appreciated.

Thanks in Advance,
Abey Tom
