Camera Raw 5.3 insufficient memory

Question

I am editing a 135mb rgb tif in CR. Adjustments are successful but saving out fails due to insufficient memory message. Win xp quad core 2.4 4mb ram

Answer 1

Forgive my ignorance, but I'm still a wee bit confused.
Firstly, I should have written in my last post (which I can't edit for some reason, though I can edit all my other posts) that, with PS open, I can open a TIFF in ACR by choosing File/Open As (not File/Open, as I wrote above) choosing 'Camera Raw' from the Files of type menu and then highligting the file and choosing open. All very well and all as described here> http://kb2.adobe.com/cps/404/kb404656.html
However, oddly, unlike when I choose File/Open, the File/Open As option does not appear to allow me to choose a bunch of files from the folder (via Ctrl and clicking on each in turn) and then open them in ACR - only one at a time. Since I use ACR via Bridge for applying general changes to an entire folder of TIFFs (after they have been processed in Flexcolor), being able to open more than one at a time is crucial for me.
Please tell me I'm doing something wrong. Otherwise, I'm going back to 5.3.
Thanks.

Sorted!
I've left my post above un-edited in case it might be of help to those who were having the same problem. But, here is the solution.............
1. In PS, under Edit/Preferences/Camera Raw, under Jpeg and TIFF handling, 'Automatically open all supported Jpegs/TIFFs' *must* be selected in the drop down menus, not 'Automaticall open Jpegs/TIFFs with settings', which is what was selected on my computer (is that the default setting?).
2. Now when I choose File/Open (not File/Open as) and then 'Camera Raw' from the 'Files of type' drop down menu (leaving All Formats selected does not make ACR an option when you click on a file and choose 'Open with ...') I can Ctrl/click on a bunch of images and they will all open in ACR.
I just tried this on a folder of 14 220Mb files followed by a folder of 18 220Mb files. I made a change to them in ACR and then saved them. It ran through them like a train! If I had tried this via Bridge, it would have choked on any more than four or five files.
One very happy camper! ;-) I'm now getting full use of my x64bit/8Gb setup. Thanks to Jeff for bringing this neat work around to my attention.
Two further points:
1. In PS, after choosing File/Open, with 'All formats' selected, it would be nice to have ACR as a choice under 'Open with....' rather than having to select Camera Raw in 'Files of type'. Is it possible to edit the selection of programs offered in the 'Open with...' menu and add ACR?
2. When opening a large number of large files in ACR, the yellow triangle with the exclamation point appears over each file and disappears as each file is cached(?). The only way of knowing if the files further down the list have settled is by either scrolling down through them, or checking to see if the green light on the front of the computer tower has stopped flickering. It would be nice if ACR had something on screen (similar to the rotating circle that appears in PS when you are saving changes to a file) to indicate that it has done its thing.
