When opening a StreamAuthor4.0 presentation under the environment of Windows XP SP2 and IE7.0, it is blank page and warning dialog.

There are some workarounds for users currently.

1. a. Close information window
   b. Click warning dialog
   c. Click "Allow Blocked content..." 
2. To avoid the warning dialog appear, we suggest
   a. Change Tools -> Internet options -> Advanced -> Security
   b. Check "Allow active content to run in files on my computer*"
