i use GLUT popup menu in project.
In the application, build on OptiX 3.6.3, popup menu works normal.
In the same application, build on OptiX 3.8.0, i recognize a little change of behavior of popup menu:
if to push down right mouse key - popu menu comes normally, but if then push up this key - popup menu disappears immediately. So, it is not convenient to choice an entry in menu.
How to get the normal behavior of popup menu?
Could it be that the two GLUT versions are different?
Please check the GLUT DLL version info and if they are different, try to use the DLL version which works the way you expected.
