An Application modal dialog is supposed to block all the windows in the application and none of the components in the blocked window must be clickable when the modal dialog is active. But List scrollbar can be moved & able to read the contents of the List.

This works fine till Mustang b42, but fails after that. So this must be introduced some where after b42. Hence this is regression.

You can see some similar bugs like 6389508 & 6408057 are in windows. but bugs is on solaris & linux .

Step to Reproduce:-
------------------------
1) Run the attached progra.
2) Click on 'Get Dialog' button. You can see modal dialog.
3) Click on the List scroll bar. you can move the scrollbar . If you see the same, the bug is reproduce.
