I tried reproducing it on other machin but couldn't. But on this machine, I can reproduce this issue everytime.

I am not sure if there could be some more machines which can have simmilar issues or not. But, we should inverstigate this issue.


How to reprodcue this issue

1. Install 6u10 and onwards release of JRE (Base JRE). I used 6u15 JRE for this test.
2. Launch Swingset2 demo application. (Base JRE's Java.exe should be used)
3. Launch FF Browser which loads some applet. (http://www.babynamewizard.com/voyager).
4. Invoke the installer (6u18).
5. Navigate through the installer.
6. Click Cancel button on FIU dialog

I could reprodcue this issue on the same machine with the Application and Browser versions of FIU dialog.

Expected Behavior:
Verify installer is exit.

Actual Behavior:
Can't cancel the installer from FIU dialog.

Machine details:
VNC : jlab408.india.sun.com
PWD is : vnc123.
I tested with offline installer (jre160.exe). I used 6u18 b03 PIT build. I guess FIU fixes are went in 6u18 b03 build.
