Cannot download or export the NAS file from iChain server GUI with IE7

When trying to download a NAS file with IE7 using the steps below, the page beeps and goes away:

1) go to the system - import/export page
2) select a nas file and click the download button

This does work for Firefox and IE6.

Change the IE security settings. We have found that this is being caused by security settings for IE. To get around this we need to set a custom security level, and under the downloads section enable the "Automatically prompting for file downloads" setting
