I remember this problem being reported from time to time in the past. I don't ever remember there being a resolution to it.
Make sure you have the latest updates for Camera Raw and Photoshop installed. That would be Camera Raw 6.7 for Photoshop CS5.1.
Can you please download and install the leatest version of camera raw for CS5. (ACR 6.7) and try again? Go to help>updates and install the plug-in. Thanks.
I'm running ACR 6.7 already.
Photoshop and Vista 64 updates are all current.
Please try the following workaround on Vista: "Select a folder (for example C:\foo), and double click it to go in the folder", skip the second part. Instead of double-clicking on the folder to navigate into it, simply select it then click "Select".
In ACR I select SAVE IMAGE
The SAVE OPTIONS Dialogue Box opens.
The default view is DESTINATION - SAVE IN SAME LOCATION
To the right of the SELECT FOLDER button is the path to the folder which contains the file that was opened in ACR.
I change the destination to SAVE TO N EW LOCATION
The SELECT DESTINATION FOLDER window opens which shows a wndows explorer view of my complete file directory on the left, with an empty pane on thr right.
I select my new destination folder from the list on the left.
The selected folders name shows in the botton dialogue box labled FOLDER
I click the SELECT Button on the lower right corner, which brings me back to the previous windw which is the SAVE OPTIONS Dialogue Box.
BUT the file path does not show to the right of the SELECT FOLDER button.
That area is blank.
It makes no difference if I single click or double click to select my new folder.
++++++++++++++++ Here's Some New Information ++++++++++++++++++
When the SELECT DESTINATION FOLDER windows opens, and my new destination folder is selected, the right window is empty, even though that folder does contain image files, and the dialogue
No Items Match Your Search is displayed at the top of that pane.
It's as if ACR opened a Search rather than allowing me to select a new folder.
