Hello,

The below code was written by someone else and basically it's constructing a URL to a page that downloads a file. Generate() is called by a button click on a VF page. After the button is clicked the user is presented with a white/blank browser page while the file is downloaded. The user then has to click the browser back button to return to the page they clicked the button. I would prefer to have the user stay on the Salesforce page when the button is clicked and have the file download. Any ideas what I might try?

The custom button was set to open in a new window and I changed it to display in current window with sidebar. The URL for the button is /apex/ReportParm?Id={!Custom_Reports__c.Id}&Name={!Custom_Reports__c.Name}&URL={!Custom_Reports__c.Report_URL__c}

Note, the sidebar does not display when the button is clicked...just a blank, white screen.
