Version: 2.7.2  
System: Linux Mint 16

If I first disable the mouse cursor with glfwDisable(GLFW\_MOUSE\_CURSOR), the callback registered by glfwSetMousePosCallback() is still called as expected, but the mouse coordinates do not update consistently. That is, they hardly change at all. It works on Windows MinGW, however.

Am I doing something wrong?

This seems to have been fixed in 2.7.3, using tests/peter.c for validation.
