Reinstallation dialog should disappear as soon as the the user is responded

Tested OS : windows
Tested bundle : mustang b87

Steps to reproduce :
1. Install mustang jdk build 87
2. Try to reinstall the jdk using the same bundle
3. The following dialog will be displayed with Yes and No buttons :
"This software has already been installed on your computer. Would you like to reinstall it?"
4. Respond the dialog by clicking yes button.
Reinstallation is proceeded but the initiated dialog is not closed.

As soon as the yes button is clicked, the dialog should be disappeared. Instead it takes long time to disappear.
It looks like as if the user is not responded the dialog.
