Can PhotoShop Elements 11 save Organizer Albums in a format PE Version 8 can open/use?

Question

I haven't found much info on how the Organizer function in PhotoShop Elements has changed from version 8 to version 11.  I've started scanning some photos into PSE8's Organizer, and it works well, but I'm considering moving up to version 11 before doing the bulk of the project.  However, I'd like my sister to be able to use my old copy of version 8 to be able to deal with the albums I'm creating with Organizer, so I need to know whether version 11 can save its Organizer files/albums in a way that is backward-compatible with version 8.
Anybody know?

Answer 1

Thanks for the response.  I suspect that you're right about the lack of backward compatibility - I didn't see anyting in the save/backup process that looked like it was giving any option to go backwards, and I would assume that trying to open a catalog with version 8 that was created/backed up by version 11 would not end well.
I suspect that the thumbnail creation issue was probably caused by the same setting that caused version 11 to copy all of my media files to a new location during the conversion process.  I was trying to make sure version 11 didn't change or write anything to any locations where version 8 was located, and something I did or checked during the conversion process probably caused version 11 to basically start over fresh and have to create all new thumbnails.  It wasn't that bad, and only happened that one time at the beginning - once it was done all the subsequent times I've opened version 11 have had the thumbnails there without delays.
The biggest time-negative thing I've found so far with 11 has been the time it takes to bring up a clear picture when double-clicking on a thumbnail - I get a full size image pretty quick, but it's blurry - then a few seconds later it finally gets focussed/sharper.  I did just find a way to list the people tags down the right hand side like they were in 8 - they can't be right-clicked and added like in 8, but they can be dragged to the photo to add them so it's almost as good.
You mention bug fixes and stuff - is there anything that the version 11 organizer actually does better than the version 8 one (in terms of handling bigger image files, or a larger number of files without choking or other such performance/stability aspects)?  I don't use Elements' editing functions (I use regular PhotoShop if I need to edit anything), and I don't use any of the web-sharing or other online aspects of the Organizer, so I'm just trying to compare how the two versions' Organizer works from a purely private, offline image scanning and cataloging perspective.
Also, the new interface with 11 seems to be eating up almost half of my screen (side to side) - it won't let me make the left hand pane (that shows album or folder view trees) nearly as narrow as it could/should be, and because the old version 8 properties box is now part of the right-hand pane/column in 11 instead of being separately placeable anywhere on the screen, I have to make the right-hand pane very wide to be able to see and type in all the file names, notes and captions, so there's very little room left in the middle for my actual pictures to be displayed.  Are there some interface-changing options I'm missing to try to recapture some of that real estate for my photos to be shown?
