Hi, I've been using mainly the 1.4 server, so I haven't looked at the border problem in a while. I just tried with the recent 2.4.1_alpha and the 1.6 and 1.7 servers, and I'm still seeing some problems with border handling. With the simple border.c example that I had sent you, the borders are shown mostly ok when the window is first shown, but if I drag the handle in the lower right to resize the window as small as possible, and then drag the handle to make the window large again the border does not show properly anymore. This is with the 1.6.5 and 1.7.0.901 servers. The exception is if the window is placed all the way in the upper-left corner of the display. Then, the internal border is always shown correctly even as I drag the handle to resize the window. So, if you run the border.c program, move the window away from the upper-left corner of the display, and then drag the resize handle to make the window small and then large again, you should see that the border is no longer displayed. Thanks for working to try to fix this problem, Martin
