Focus weirdness

["David Munger" <mungerd gmail com>]

Hi,

I'm having a weird focus problem with an xterm embedded in a GtkDrawingArea.
When I put the main application on sleep, the xterm can get the focus.
Otherwise, it can't.

Could somebody suggest me a way to allow the embedded xterm to get the focus
when the GtkDrawingArea gets it?

A minimal example follows. Move the focus in and out of the window. The main
application will be put on sleep for 3 seconds when the GtkDrawingArea gets
the focus. During these 3 seconds, you can type in the embedded xterm. When
the main application wakes up, the embedded xterm loses the focus.

Thanks in advance for any help!

David
