Re: Dialogue Screen Placement

["Richard Boaz" <riboaz xs4all nl>]

Below is a small program demonstrating my problem.

My window manager is Gnome v2.10.0.

In the program, I have set both the main window and the dialogue window to
be positioned at the center of the screen.  Interestingly, for the main
window, this works fine; it is only for the dialogue that the position
command seems to be ignored.

Any ideas why this is behaving so?

All thoughts/input appreciated.

cheers,
