Summary: Updating FVR from Modeler doesn't work

Initial Comment:
The symptom here is that when you intitally create an
file variable file (FVR) it is editable and saves
correctly, but thereafter it appears to revert to its
original contents sometime after you try to update it.

Here's what happens:  When you open a script in the
Commander for the Modeler to edit, a temp dir is
created in Repository\.TMP\ called CYR???.tmp\ .  Into
this dir are copied; the scripts .ALL file from
Repository\Captures\
, the actual SCL script (.HTP) from Repository\Scripts\
and any referenced .FVR files from Repository\Data\ .

While you are editing your script, if you compile
and/or run it then this temp copy is updated.  When you
run the script from the Modeler it uses the files in
this temp dir - except the .FVR files which are used
from the Repository\Data\ directory.  Any edits you
perform to the .FVR using the GUI are also performed on
the copies in Repository\Data\ .  So if you edit an FVR
then run your script you won't see an issue...  Here's
the crunch though - when you save your SCL script in
the Modeler the files from the
Repository\.TMP\CYR???.tmp\ are copied into their
normal places in the Repository!  And yes, this
includes the .FVR files that have been saved from when
you first opened the script... :-)

I guess that GUI editing and running were supposed
action on the Repository\.TMP\CYR???.tmp\ copies of the
.FVRs.  The fix could make this happen, or simply get
rid of the .FVRs in this temp dir...  I'd like to hear
opinions on which of these is preferable from the user
point of view?

Workarounds:
 - edit .FVRs by hand with Modeler closed
 - delete .FVRs in Repository\.TMP\CYR???.tmp\ after
starting Modeler

I'm reproducing similar problem2 with OpenSTA 1.4.3.20 on
Windows XP Home SP2, but the workarounds mentioned here
aren't helping much.

Usually I simply attempt to edit the .FVR files using the
vim editor, independent of the Modeler.  Shutting down
Commander and the Modeler and deleting files under .TMP is
not sufficient to get the Commander to find the new data. 
The Modeler seems to be much quicker at finding the updated
data.

The best workaround I've found is to shut down the
NameServer and restart it.  I can't find any place in .TMP
or anywhere else on the disk where the old contents of the
file are cached, so I think it's the NameServer that's
keeping the old data in my case.
