screen saver : loading photos too long with aperture 3.3.2

Hi,

I've upgraded to mountain lion today and I've discovered an issue.

Screen saver does not display my aperture library (though I can select the aperture library and see clearly the photos inside)

It says 'loading photos' with a black screen and nothing more happen.

When I select a folder with small amount of photos (less than 10 for exemple), it finally works.

But I like to have my whole library targeted for screen saver.

I add that it was perfectly working before the upgrade, and Aperture was already in 3.3.2 before mountain lion upgrade.

Lion screen saver was working perfectly with my all aperture library and now it's a disaster.

Moreover, the new slideshows added in the screensaver are worse than the one with Lion. I particularly appreciated the "Polaroid" pictures with the date below.

Now I cannot have it anymore..

So I have two questions ;

1) Is there a way to speed up the loading of photos for the slideshows of screen saver ? A cache file ?

2) Can I get back the previous screen saver of Lion ("polaroid" pictures with date below)

thanks a lot for your help

I'm a newbie in Mac 🙂
