My fear of "Upgrade" came full circle this past weekend. Having experienced problems every time I upgrade PSE (from 4.x to 6.x to 8.x), I decided to purchase a complete DVD set for PSE/PRE 10. For me, that's a 60+ mile round trip to Fairfax, VA's Micro Center. I was successful at installing PSE 10, but very unsuccessful at installing PRE 10. After accessing Adobe's Chat service, I was told to call back on Monday for technical support. Because I did not want to wait until Monday, I decided to download PRE 10 (trial version) with the hopes that it would be a later version than the one I had on DVD. After 10 hours of downloading, it proved to be a better version and did install. So now, I have the DVDs for PRE 10 that are useless if I ever want to reload my PRE 10 again - would it be possible to get replacement DVD for free(?) I then started using PSE 10 only to find that the feature activated via "Preferences" called "Folder Location View" which I've been using for several years (PSE 8.x) was NOT listed in the Preferences for PSE 10. I spent another three hours searching blogs for possible solutions - - found that the single command: "Option-Command-3" did the trick (would have been nice to see the option in Preferences). So far, I've only noticed one reportable bug: After using PSE, and doing a 'save-as' to a different folder than where the RAW photo is stored to a .jpg file; then closing the PSE editor. The next time I use the editor, that .jpg file is still open after I open any other RAW file.
