I've tried Bibble as a Trial and now have ASP - works great on my win 64 newish but low end lap top. Last weekend I imported 19,000 photographs into a catalog - no problem, After all this was done I opened up the program and clicked to view a tag with over 2,000 images, the tagged images came on screen almost instantly. I tried another tag with 30 images, same thing. Now I'm making changes to my tags for better results. Next week I'll start adding my other external hard-drives.
