I'm using Dokan SSHFS to mount my Linux server as a drive on my Windows 8 laptop.
Other programs, (eg. SkyDrive Win8 Store App or native Win8 desktop apps), can access this mounted drive and open and change files on it.
Code Writer lets me browse the drive with no problems, but closes immediately when I attempt to open any file. I have Code Writer set as the default app for my files, and opening the file from Windows Explorer on the desktop also causes Code Writer to crash.
Steps to reproduce:
Install the Dokan 0.6.0 library and then install win-sshfs 0.0.1.5 as detailed on http://linhost.info/2012/09/sshfs-in-windows/
(Note that upon first running the Dokan installer, it will say that the operating system is not supported and exit. Windows then asks if you want to install in compatibility mode, and the installer then works.)
