I don’t know of a memory leak, but the latest version is 9.0.2

Also, you haven’t defined exactly how you’ve determined that there’s a memory "leak" that all of us have apparently missed <smile>.

Tony, there was a thread that seems to be gone now in which several users, including me, working with Scott Byer, confirmed the existence of a very specific type of memory leak  not the usual complaint that memory isn’t released when images are closed, but something very esoteric when certain extras were cycled between being displayed and not, or something like that. It may have been GDI resources instead of memory. This was long enough ago that I’m sure it was addressed in 9.02, if not 9.01.

Well if that’s the case Michael, my apologies to the OP. Thanks for letting me know.

Sorry for not being more specfic…I will try and explain better.. When an project is opened and a few layers are added my available ram starts to increase to extremly high useage 1.5GB or more… I will admit my files are large some reach to around the 200MB size..But the amount of ram stays at that level even if I close the project I am working on and start something smaller the ram useage never seems to go down… I have even noticed the ram useage slowly creeping up EVEN IF i AM NOT WORKING ON THE PROJECT {SITTING IDLE}
HOPE THAT CLARIFIES THE PROBLEM…
thanks in advance

I have experienced a similar thing recently (Photoshop CS2 9.0.2, Windows XP SP2, 1 GB RAM). I was running a self-made script that loads an image file and rescales and sharpens it to four sizes, saves them, and then releases the original file unchanged. The script applies this task to all image files in a folder.

I pointed the script to a folder containing 85 JPEG files at approx. 2 MB each and ran it. While processing one image, memory usage goes up to approx. 64 MB and goes down again when the image was done. However, while processing one image after the other, memory usage went up at a rate of an additional 0,2 MB per every three or four images. Obviously, a few dozen KB of RAM per image went out a leak.

This Knowledge Base document: <http://www.adobe.com/support/techdocs/320005.html> explains Photoshop’s unique handling of memory.

Once I’d got my head around the fact the Adobe engineers have done this for very good reasons, I stopped looking at numbers and concentrated on using this excellent imaging program for.. well… imaging!

Olaf – no, what you are describing is expected behavior. Photoshop uses memory up to the limit you specified in preferences. It doesn’t release memory, it reuses the memory.

But increasing memory usage while sitting idle could be a couple of things: font previews building in the backgroun (should be small amounts, and stop once all the font previews are built), Photoshop cleaning up image memory usage and writing things to disk in the background (should settle down after 10 seconds or less), or a previously undiscovered leak (which could be in the application, or due to some third party interference).
