Root Folder Sorting

I'm not sure if this is just my installation or if everyone is seeing this, but my root folders are no longer sorting alphabetically. Instead, they are sorting by creation date (I think).

Is this by design? If so, is there a work around?

We have a large number of root files, so this makes finding things difficult.

My environment is:
> FV 4.5 (upgraded this past weekend)
> Server 2008 R2/IIS7.5 (web)
> Server 2008 R2/SQL 2008 (db).

Yes, you are right sorting was disabled in v4.5 by accident. We have addressed the issue in Fix 1:
Fix 1 for FileVista v4.5 (v4.5.1)

Thanks Cem...that did the trick!
