Ok everybody, it's fixed. Yay! For a totally different reason (I could not easily see the little 'X' for closing tabs), I switched from 'SeaMonkey Default Theme' to 'SeaMonkey Modern'. After restarting, the problem was fixed. I can also see all the little arrows and things that were supposed to be there.
Thanks to Jay and Paul for responding. David _______________________________________________ support-seamonkey mailing list support-seamonkey@lists.mozilla.org https://lists.mozilla.org/listinfo/support-seamonkey
