(This test verifies that modal dialog can be made always on top
This test should only be run on the platforms which support always-on-top windows
Such platforms are: Windows, Linux with GNOME2/Metacity window manager,
Solaris with GNOME2/Metacity window manager
If you are not running on any of these platforms, please select 'Pass' to skip testing
If you are unsure on which platform you are running please select 'Pass')
1. After test started you see a frame with \\"Main Frame\\" title
It contains three buttons. Every button starts one of test stage
You should test all three stages
2. After you press button to start the stage. It shows modal dialog
This modal dialog should be always-on-top window
3. Since it's a modal the only way to test this is try to cover it
using some native window
4. If you will able to cover it be native window - test FAILS, otherwise - PASS
Note: in stages #2 and #3 dialog is initially shown as regular modal dialogs
You will see \\"Let's wait\\" message in the message area below
Please wait until message \\"Let's make it topmost\\" will be printed in the area
After that you can continue testing.
