Thanks for the help guys!
	
I have managed to get my links showing as I like, but I have problems with the mouse-over effect... It's working some-what - But I can't get the mouse updated as it should.

I am checking for the event GDK_MOTION_NOTIFY, (through a g_signal_connect with "motion-notify-event" and then use gdk_window_set_cursor to update the mousepointer, but as I said, it doesn't actually update the mousecursor until I either click on the text, or press a key on the keyboard. I would like it to change by just hovering above the links.

Has anyone run into similar problems?
