How does one check the progress of the file loading?
User clicks link on web page to open Excel file in a new browser window.
File sizes can be 2MB + . Over a crappy connection they could take 10-20 seconds to load.
Looking to do...
Pop another window (gets focus) that has a static image that says something like "Loading....This could take up to a minute."
Once the Excel file is loaded into the new window, signal the popup window to close.
