I have a dialog which uses toggle frames and toggle buttons. The program works fine with mingw on Windows and gcc with Athena on Linux. With lesstif however, two problems occur: 1. a toggle button when pressed turns black and does not show it's text. 2. when I toggle a toggle frame the whole dialog disappears and will not reappear. Has anyone seen this? Cy Ball cyball@dimensional.com (303)751-2678
