It looks like you have a very wide User Description column that is taking up all the space.
It's hard to suggest what to change without being able to see how you have configured all the columns.
I think I managed to fix that, I set user description to the same auto and fill (don't know why that fixes it, but it does). Anyway, problem is now how to apply auto and fill to every single folder on the system?
Leo, does "Expand" just use up the remaining space? If so, does it work better if the expanded column is the right-most column?
I'm thinking in blueloo's case, his User Description column was set to Expand and it was squishing the other columns as a result.
blueloo, can you post a screenshot of your Folder Options settings? I'm curious how things are set.
