Splash screen in lateNight doesnot show progress with progressbar

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Run the application
2. Login
3. Look at the progressbar (part of splash screen).

What is the expected output? What do you see instead?
Progressbar is set with IsIndeterminate="True", hence expect the 
progressbar to show the progress animation.
But Progressbar with any other animation, doesnot get updated.

What version of the product are you using? On what operating system?
latest-LateNight_v0.4_(r85)_src.zip

Please provide any additional information below.
I tried using the same methodology to display splash screen in NON-CAL 
based application and it works perfectly fine. But when we try to use any 
animation/ set progressbar value...no results/UI update.. It looks like 
CAL disables all UI update while it is loading modules. Is there anyhting 
that I need to do with CAL to make these animations work?
