Texturing problem (4)

When I drag a simple material onto an object it works just fine, like a green blinn for example. But when I adda texture like a ramp, file or anything else they don't show up in the viewport, but they render just fine. I tried deleting the prefs but that didn't work. What should I do?

Thanks in advance.

Hi.
You can press "6" or "7" key. (7 for Texture with lights.)

Thanks.
