Hi.

I appreciate your kind suggestion, but that seems not to be the proper solution yet.

For sure my window was focused when I move mouse pointer on it.
The strange thing is that if I connect "motion-notify-event" signal to my TextView,
the callback would be invoked only when the mouse pointer's entering the window
as if "enter-notify-event" case.
Similarly, the 'GDK_MOTION_NOTIFY' type event would be caught only after
I clicked the TextTag.
My vague reasoning for this phenomenon is that TextView might block
emissions of "motion-notify-event" after a certain operation.

I did that, but that seems not to be working.

My working platform is Solaris 2.6 / Sun Ultra Sparc 10. Can it be the source of my problem?
