When I switch to the 3d lightmap view, It just goes black and white flat shading, no lightmap grid! Did I hit a hotkey or what?
So Nobody Out There Has Ever Seen This Happen!?

Its been like this since the last SDK update, if you really need the lightmap grid you can use the "-engine EP1" lauch option. This will run the SDK in the previous sdk settings (ep1) your map will be missing all TF2 models and textures but atleast you can adjust the lightmaps now 
lightmap grid works fine for me. i don't know how to solve your problem, but i can at least tell you that the lightmap grid should indeed work.
thanks for the replies, I guess for the final render of my map I can always try reinstalling hammer.
It just doesn't show the grid, you can still edit the lightmap settings.
Yeah but my map is not just a bunch of square boxes. So it'll take quite a bit of a pain in the ass to do it that way.
