I'm using the Lispworks IDE on CentOS running on VMWare Fusion on my Mac.  The is a shared file system mounted that I can read and write from both my Mac and my VM.  LispWorks refuses to write anything to the file system!  I want to use the Lispworks IDE to edit files there.  Other tools such as EMACS can read and write files on the shared filesystem.  

In case it matters, the file system is at /mnt/hgfs, and I'm using a symbolic link to get at a directory inside the file system.  But it doesn't work even if I don't use symbolic links.

I've tried changing permissions and restarting the VM, and I haven't been able to get it to work.  Other tools can write files, why can't LispWorks?

Thanks,

Jeremy
