Modal shell not working properly

Java

dialog

I am using the following code:

Shell parent = getParent();
Shell dialogShell = new Shell(parent, SWT.DIALOG_TRIM |SWT.APPLICATION_MODAL);When I minimize the application the child dialogshell also gets minimized. That is ok(expected behaviour), but while using tab the child dialog shell sometimes appears in front of some other application.

I want that child dialogshell to be tightly coupled with the application only and should not appear with some other application open in the browser.
