Lightroom 4 Beta works great on my laptop, where I don't want to use it. On my desktop, it is a complete waste. I have posted on the Adobe forum, but no help there.
After editing any image for a while, especially after going into the details panel, I get the message "There was an error working with the photo," and then that is it for that image. No more editing of that image is possible. By this time, and often before, the image in the editing window appears to be a low-res version. It is clearly lower-res than the original when you zoom to 100%. It is like the original file has been replaced with the JPEG preview. Oddly, at times the image in the second monitor (just a loupe view) remains hi-res.
In any case, I have not been able to find anyone who has any ideas of what is going on, although there is a thread on the Adobe site of someone with the same problem in LR 3.3. That thread yielded no good advice either.
Does anyone here have any ideas what might be going on? I sure don't want to screw with upgrading if a problem that has been around since 3.3 is going to make it into production!
Thanks.
