Multiple file downloads using force_download()

[eluser]tomgkelly[/eluser]
I'm developing an application that allows users to download files. The user selects files from a pseudo catalog and they're place in a cue. When the users decide they've selected what they need they hit the download button to download all the selected files.

Everything up to the download operation works fine, but when the download function executes, only the first file in the cue is downloaded.

I'm using the force_download() function (from the download helper) in a loop in conjunction with an array that supplies filenames etc. The loop executes through the first iteration and then exits after the force_download() call.

Anyone have any ideas?

Thanks in advance
