The demo events.c:

glfwSetKeyCallback(window, key\_callback);

When I ordered the left key of mouse, and then move the mouse, then release the mouse,then this function will also play a role.I think is a bug.

then I have debug this func,this is the results ：

```
if (key==345&&scancode==29&&action==1&&mods==2)
	return;
if (key==345&&scancode==29&&action==0&&mods==0)
	return;
if (key==345&&scancode==0&&action==0&&mods==0)
	return;
if (key==67&&scancode==46&&action==1&&mods==2)
	return;
if (key==67&&scancode==46&&action==0&&mods==2)
	return;
```
