@Michelle: thanks for not-paddling g. It seems to be independent of other progs. Happens with lots of programs open but with none of em too. 1 GB RAM should be enough but with Win XP i'm not sure any more. @Wivelrod: that option was turned off already. Did it again and marked "use on all folders" and at least that reloading seems to be gone. I may be wrong but the thumbs are loading somewhat faster now too. Using PS 6.0 myself. Unchecking "generate thumbsnails" provides the same problem as the idea from 3DGuy - no thumbs any more. @3DGuy: details are great on a lot of folders, yep! But as i don't touch my original shots i don't rename them and filenames like 123_4567.jpg are not helpful in finding the pic i'm looking for. Secondly, even without thumbs (e.g. in detail view) i have to wait that 2-3 minutes until all files get there PS-icon. They can be double-clicked before but it's visible, that Win XP is still working on that files. Strange, isn't it? Thanks a lot to you three!! :-)
