Are you using referenced or embedded mxm's?

If referenced, you have to set the active map inside the Maxwell Material Editor.

If embedded, you must click on the map slot you wish to see in the viewport, then click the "show map in viewport" button.

It actually works just like previous versions of Max.

Unless you have some setting in Max to disable bitmaps in viewports, I can't think of any other reason why you can't see them. I'm using Max 2010 32 and 64 bit and have no problem seeing maps in viewports.
