Marcel, on my wife computer (PIV 3.6Ghz + 512 Mo), a folder with more than 200

This problem come when i toggle betwen another album and i'm back to the RAW 

I need more investigaution about, but certainly a settings about can need to 
be done, for example to set the number od thumbs need to be cached.
