[filmscanners] RE: Photoshop freezing

["LAURIE SOLOMON" <laurie@advancenet.net>]

I believe that your so-called clue is a normal condition and one of the
reasons why one requires a large scratch disk of unfragmented contiguous
space usually 3-5 times the size of one's actual file size.  You do need to
turn virtual memory on so as to use the scratch disks.  The 120MB of
physical RAM is really very little in the scheme of things with contemporary
machines having up to 3GB of physical RAM with as much as 1GB asigned to
Photoshop. However, unless you are working with 3 or 4 100MB plus files
during a session, it should not cause the Photoshop to freeze once you turn
the virtual memory back on and assign Photoshop a sccratch disk space one a
hard drive with some free contiguous unfragmented space of around 100MB or
more ( better yet assign the scratch disk itsown dedicated hard drive or, at
least a dedicated partition on a hard drive).

>There is 304MB installed RAM of which 120,000MB are assigned to Photoshop.

I assume that the 120,000MB iws an error and should read 120MB; otherwise
that is your problem, you are trying to do the impossible. :-)

You also might check to see if the files which are to be saved are flattened
files since sometimes undesr some settings one cannot save unflattened
files;  files that are 42 bit as oppposed to 24 bit also cannot be saved to
a TIFF format.

Subject: [filmscanners] Photoshop freezing


I've hired a graphic designer to scan and colour correct some
transparencies using Photoshop, and I have set her up on a new Epson
3200 scanner, and a PowerMac 9500 upgraded with a G3/400/1MB card,
and running Mac OS 9.1. (I had never used Photoshop myself, but I
seem to be the tech support person for all the Macs around here).
There is 304MB installed RAM of which 120,000MB are assigned to
Photoshop. Virtual Memory is off.

Today Photoshop kept freezing. It seemed to work fine for the first
file opened and adjusted, but it always froze during the "Save  As"
of the second  file. The files are in the range of 20 to 40 MB in
size.

Following is what happens. Open a Photoshop TIFF file, make some
adjustments and save it as under a new title and then close it. Then
when another TIFF file is opened, everything is the same up until the
"Save As" operation. When the dialog appears asking whether to save
as a "PC" or "Macintosh" file, the program freezes as soon as
"Macintosh' is clicked leaving a white space where the dialog had
been.

Any ideas?

CLUE
  (A) I've checked with Memory Mapper, and find that Photoshop does
not release the extra memory a file used when that file is closed. It
hass to be quit and re-launched in order to release the memory.
