Paths with whitespaces in ido (find-file) (on MS Windows)

Question

I am running GNU Emacs 23 on a Windows-machine and having problems getting ido-find-file to match files that contain whitespaces.

In my .emacs I (setq ido-use-filename-at-point t) and would like to match a string like "D:\Dokumente und Einstellungen\Username\Eigene Dateien\Scratch\ipswitch.bat" when hitting C-x C-f.

When point is located between " and D:\, IDO suggests d:/Dokumente[Dokumente und Einstellungen], i.e. the pattern "breaks" on the whitespaces.

I would like the whole string (maybe restricted to certain modes (like org-mode) if that is necessary) to be matched and suggested.

How could I get that working?
