IDE & Appbuilder bug ?

Is this a bug ?

If I create a phab project and then move it using the navigator move
menu option to a directory outside of the workspace, say /tmp/tt. I can
compile the program but I can no longer load it under phab, phab starts
up thinking I have not created a window yet.
If I try and create the window it says “AB: Unable to make directory
//tmp/tt/wgt - No such device or directory”, even though it does exits.

I’m using the windows hosted eclipse.

I cant edit the files either if I run Phab separate from the IDE as it says
application was created with the Eclipse tools, etc, etc. I can re-edit the
files if I move them back to the workspace directory.
