Hey all, I''m trying to get a GLUT program with 2 separate display windows to share the same variables (made global for testing purposes). What behavior I have seen exhibited is as follows: 1 - the globals, ''g_iMouseX'' and ''g_iMouseY'', are updated inside the GLUT passive mouse callback function if code is placed inside this function. 2 - when the code execution point reaches the GLUT draw callback, the variables'' (from #1) values are 0. Any ideas? MatrixCubed
