When I choose the coverflow mode with all my library (more than 1800 items),
the cursor is turning endless with the colour weeling, and the application doesn't
respond anymore (the process is at 9x% of CPU, and I have to kill it).
After that, I have to backup a previous library (thanks to time machine

because the option view stays in coverflow mode ...
I run on Mac Pro 2008, 2 Go RAM, Leopard 10.5.3
Thanks for fixing that.
