This bug appeared in rox-2.0.0 (the current stable version) when upgrading gtk-2 to version 2.2.4-r1 : the scrollbar on the right in Rox-Filer does not work : it is present but uses 100% of the height and cannot be moved, so files and directories outside the range of the window cannot be accessed. This is resolved in rox-2.0.1. Time to mark it stable for x86 ?
marked stable :)
