I'm trying to open a internal folder on one of our servers from Salesforce by way of clicking on the custom links in the left nav. I have it working-ish , but am getting a blank IE pop-up. the behavior that i want is that the user clicks the link, stays on the current page and the folder location opens up in a new window. the bug I have is that there is an unwanted IE pop-up. I'm guessing there's some issue with an IE window vs file-explorer window.
The way i'm implementing it is my content source= URL and the behavior is display in a new window. the URL = 'file:///Z:\myServer'
any ideas?
UPDATE Here is a screen shot
