Apparently Microsoft made a change to how the networking stack in Silverlight works by moving it to a different thread. This was causing an exception when files were being uploaded to the server. After some investigation I was able to find a fix (thank you Google).

Feature List:

• Added several system prompts
  

Fix List:

• Uploading of custom prompts was fixed
• Import data upload was fixed
  
• Various popup dialog's edit and delete commands were not functioning
• Fixed playback of system and custom prompts
  

I spent some time redesigning the look and feel of the user interface. The color selected is a bit special. I can't tell you why yet, but it is special - really.

Feature List:

• User Interface (UI) theme and fonts updated
• Data dialog overhauled into a tabbed dialog
• Test message feature in message designer updated to include the ability to select a transport method

Fix List:

• Problem with the e-mail transport was fixed
  

A new feature to was added to inphoniteNotify - the ability to test a message. If you look at the Message tab under Actions you should now see "Test Message..." When you select this link it will prompt you to fill out the data dialog. Once you hit save the message will be sent. As an added bonus the data you put into the data dialog will be remembered the next time you want to send the message. Give it a try!
