    Two open & working catalogs in Lightroom 5.5


      Is this a new feature or a bug? I was reviewing my students catalogs and when opening a new catalog the other one does not close. Now mostly there was some message first that went away afterwards, and in two occasions the "background" catalog gave an error, but a couple of times I could just switch between the two catalogs and they were both functioning. I must say it is convenient when reviewing

      I was opening the catalogs from a rather slow external USB 2,0 drive. I've included screenshots.

      For reviewing I use AnyFilter PlugIn by John R Ellis, so not sure if that could cause it?

          Interesting. I tried (not very hard, granted) to duplicate this feat and didn't make it happen on Win 7, 64-bit.


          Having two copies of LR running on two separate catalogues probably wouldn't mess you up. Running twice at the same time against one catalogue would be a recipe for disaster, and LR is pretty good at not allowing that to happen..


          The Hacker Dictionary would probably call what you saw a mis-wart: something that ought to be a bug but turned out to be a feature.
