However, when viewing the whole board the crosshair does not always follow the cursor in the GL version, which it something that works flawlessly with lesstif. My GL driver is: $ glxinfo |grep "^OpenGL renderer" OpenGL renderer string: Gallium 0.4 on ATI RV530 Regards, Gabriel > > Regards, > > Igor2
