[GoogleCodeExporter]

What steps will reproduce the problem?
1.launch "stable" build of WBC
2.let it run
3.

What is the expected output? What do you see instead?
the 3d image of the brain. instead the splash page with the loading User

tried this on windows XP, a WIn 7, and a CentOS linux

tried this many times on the same computer, and i have also tried deleting the 
wbc cache

How's this going?

This symptom was noticed on two computers, the XP machine in the cubical right 
in front of Maryann's office and Vikram netbook. 

That XP machine is known for being unable to run the WBC, even after updating 
to the latest video card driver. In terms of the netbook, I saw Vikram trying 
to run the application with same symptoms, which just means that the video card 
does not support OpenGL 1.2+. In the netbook case it could be a bad driver in 
Windows 7. 

The error is not replicable in any other machine I have run it and have access 
it to.
Will update status to won't fix, since I am convinced this error is due to bad 
video card drivers and not our code.
