The drop-down menus don't open in some shaders.
For example :
- the displacement direction in the Displacement shader
- the displacement type, noise flavour, variation method and lead-in warp effect in the Power fractal shader
- the specular highlights in the Reflective shader
etc.
I still can use the arrows to make a choice but it's not very handy.
Am I alone to get this problem ?
Sounds like the same problem as this:

The solution is to change the Windows theme, temporarily. You can change it back to your preferred theme again if you want, and everything should still work.
