unity 3.2 reimport does nothing

I have updated a texture, clicked reimport. it then thinks for a couple of seconds, but when it’s done, nothing happens…
the log says : Updating assets/textures/dirt_road.jpg - GUID: 70aa1a199c0d08b48807702a7286c412…
done: hash - 21e4fc13bcf934531a19119de4b85811

no error, no update, no nothing…
what am i missing here?

Reimport has never worked for me in Unity 2.x or 3.x. At least on a PC.

what do you expect to happen?

for me it worked fine, given the state in editor for some reason succeeded in going out of sync

I expected it to reimport the assets from where I imported them, but upon further reading apparently that isn’t the case.
