Emacs using Ido no longer remembers buffer list between sessions

Question

When i C-x b to get the list of buffers (using ido) on my Linux installation of Emacs 24.3 i have a list of the recent buffers in grey. When i open a few buffers and the C-x b again these are now listed in white. So there appears to be two groups of buffers in the buffer list - 'opened this session' and 'opened previously'.

I recently installed Emacs 24.3 on Windows and this behaviour does not appear. I only have a 'opened this session' list of buffers when i C-x b. How can i add the 'opened previously' list?

Answer 1

the variable ido-use-virtual-buffers causes recently opened files to be listed in the C-x b list.

(setq ido-use-virtual-buffers t)

this variable is set in the package starter-kit.
