Hi Colin and Rene,
I have the same experience on win98 when I for instance select
a DrawPanel from the menu. Frequently the popup panel overlays
partky the canvas. When I drag it to the side, the part of the
panel which overlays the canvas stays there as well. However,
when I then drag the canvas a bit, the picture refreshes and
everything is o.k. again.

                                            Cheers,
                                             Nick.
