Vista - problems with organizing files indexed locations

Hello!

I hope someone can help! I have asked this question in the Dutch newsgroup
and previously in this newsgroup but unfortunately it seems to be a rare
problem. However, I have more information now so maybe this helps!

When I choose (using Vista) 'stack by name' the shown folders are empty. It
shows a-e, f-l, m-r, s-z and also for each folder the number of items found
but when I click on the folder it is empty.
Stacking by size, label etcetera works fine: the files are in the folder
then.

I use this option very often so I would like it to work. I have also
discovered what the problem is: the fact that that the location is in the
index. If I remove 'Username' from the index everything is shown the way it
should be! Of course I don't want to turn the index off as this makes the
computer much slower. After having discovered what the problem was I have
recreated the index several times hoping that this would solve the problem
but the problem stays...

My question is: might this be a known bug in Vista? I hope someone can check
if he experiences the same problem? Then I know at least that it's Vista.
If not, does someone know how to fix this?

Thanks!
