I've tested this in the trial install (before the 6.4 upgrade) and normals show up just fine. (They are green; I did not change the color.) After the upgrade they do not show up using either Selected Normals or All Normals.
If it matters, I'm using the gxl2dx8a.dll's but the normals don't show using either (and textures don't show at all with the other dlls).
There are no problems other than this.
