Okay, let's say I've been using CS2 for a day or so, doing various things.
This morning:

1. I close all the images I've got open and open a scanned JPG image. It's
a 2-1/4" square image at 2400 DPI which, after minor cropping, is ~73 MB.

2.I create an Adjustment Layer for Levels and make the necessary changes.

3. I save it as a .PSD file with the 2 layers

4. I try to save it as a .JPG file. I get the dreaded "Insufficient Memory
to save ..." message.

5. I close Photoshop and reopen it.

6. I load the saved .PSD, flatten it, and successfully save it as a .JPG

Okay, I know that Photoshop caches some stuff, so I've set the Cache Level
in Preferences to 2 instead of the original 6. I've told the program to use
all of the available memory (100%) which it calculates as 907MB (it's really
a 1GB memory but I guess Win2K doesn't allocate all of it to programs).

It's obvious that Photoshop would have had sufficient memory to do the
original save (#4) if the program's caches had really been empty as they
were when I reopened it. Is there anything I can do between images (or
while I'm editing an image) to empty the caches or am I stuck closing and
reopening the program. This is especially important because I've been
screwed being totally unable to save an image in any format after working on
it for a while.


TIA
