Storage of Project Images

I discovered this issue when testing v11
I have Studio V10 running on Pc and laptop, I have a local NAS drive ( and also some public cloud ) which enables me to share work.
I went to open a trial project in v11 and it told me that an image in App Data \ Local \ Temp could not be found - it then hung completely needing task manager to kill it.
Repeatable hang.
Sudden realisation --- Filter Forge is saving shareable data in App Data \ Local --- consequences are obvious.
Images for a project should be stored in the project file , no? Accepted that caches can be in App Data but not the actual images or filters.
Further investigation ongoing ....

Ed. Possibly the beta 11 is allowing me to work with projects which should be sharable but is storing the information in an unsharable way because the beta licence is not flipping some switch somewhere to use shared storage. ?

EDIT - thought I had found one cause ....
If I leave a FF running on one computer, the temp files on C: are not tidied away in to the project files so opening the project on the other computer fails when trying to access them as it obviously has a different C: drive

But Edit -- this issue only needs one computer.....as I found this morning
FF10 created project on the NAS drive - including a picture from C: desktop.
double click the project and it opens in FF11 and reports the missing temp file and hangs

Please advise how to send the project file as I cannot attach it here and the normal reporting mechanism doesnt take attachments.

The cause appears in both cases to be incomplete closure of FF so the temp files are not rolled into the project.
Not easy to reproduce!
However there is an issue in FF11, in that it hangs completely (needing Task Manager abort) if it attempts to open a project file in this bad state.
