Allow windows to be opened with various degrees of opaqueness. The application running underneath would still be visable so the user could be receiving info from both programs. Imagine this : you are displaying a digitized or raytraced picture and you want to look at the CAD description of it, your engineering notes, or a structural analysis of what ever you are displaying, so you open a transparent window on top of the picture. You could see important differences and make changes accordingly. You could open a drawing program in a transparent window and sketch an outline or addition to the original picture, without touching the original. CBM please include such a feature in V1.5 (1.4 would be even better). -Brant -----Opaque Windows: the way of the future------- -- Brant Coghlan (403) 487-3619 ...{ubc-vision,sask,ihnp4}!alberta!brant Dept. of Comp.
