I use Windows Picture & Fax Viewer to review images and run as a slide show. I have a problem with recent images when I click the ikon to make the image go to 100% size - I get "Drawing Failed" instead of a 100% size image. If I rotate the mouse wheel to make the image size either less than or greater than 100% then the image appeaars and I can rotate the mouse wheel back to the 100% size and all is ok. Older images do not have this problem. I save RAW + JPG images with the camera. All images are processed using Photoshop CS2 and saved as JPG for viewing. JPG images from the camera are processed in Photoshop to change profile from Adobe RGB to sRGB, correct lens distortion, and saved as a JPG. RAW images are processed using custom settings for each image, lens distortion correction, sharpening, profile changed to sRGB, and saved as a JPG. When I view the JPG processed images I do not have the "drawing failed" problem, but do have the problem with the RAW processed images. Anyone have any ideas? I have not checked to see if the new release of the RAW converter (ACR 3.7) is the problem, but will do that today. Older images were processed using an earlier version of ACR.
