3ds max 7 Viewport, Texture not updating when saved Options

[Oliver]

Pretty much that, I had to do a clean install on my computer, and before that, the viewport updated itself everytime I saved a texture or a psd file... But now, I have to reapply the texture in order to be updated in the viewport (its the same driver as before)... Do I have to enable it, cause I dont remember do such thing before.
