There is one extra install window while installtion of JDK

STEPS :
1. Start installing JDK1.6.0_10-b25
2. After few steps (install windows), it asks for installtion of jre, say yes.

At that point of time, there are two install windows on the screen. One is having the progress bar moving and the other one is showing no progress.

The second window is not needed, if it is not used for showing the progress of the jre installtion process.
