I changed it - sorry for the wrong title.

Here are some screenshots, I hope, they explain it in a better way.
You see, if you change a block beside the wire (added a gold block), the wire updates, otherwise not.

I think, I din't explain good enough. :/ I know, how Redstone works and that nothing happens in unloaded chunks. But the wire does not update, also not when chunks are loaded then!
I will try to explain again. We have a long, long redstone wire which is not powered. I stand at the end of the wire and power it - the redstone wire is powered in all loaded chunks. Then I walk along the redstone wire (new chunks are loaded), but the redstone wire does not update in the new loaded chunks.
