Can someone explain to me why, quite at random, sometimes it will take a fraction of a second to get a sharp picture after you have clicked the thumbnail and other times it may take 15 seconds (!) before the fuzzy picture becomes sharp. This is quite erratic and totally random as far as I can judge.

  That's difficult to say without knowing more about your system specs. Could you please share them, then people have a chance of figuring this out.
  
  Quite generically, your system is low on memory, or you have a lot of other tasks running, or your pictures are on a hard disk and it's busy serving some other request (like the OS).

  Hi HCS,
  
  I have this happening both on my MBP 17" and on my MacPro 2x 2.93 GHz 6-core Intel Xeon with 24 GB of RAM. This is supposed to be the fastest current MacPro.
  
  No other software running at the same time.
  
  Cheers, Bob

  Hi Bob,
  
  Well, there is more to it than just raw processing power (although that helps a lot). 12 cores aren't necessarily making preview rendering faster, faster cores are of bigger help. Running the system and C1 off of an SSD helps too. Having a big fat graphics card helps a little too as well.
  
  I am not the specialist in the C1 area (nor Media Pro, by the way), but i am running a Mac Pro with the 6-core at 3.33 GHz and a 1GB ATI graphics card with the OS on SSD. I don't see (at any time) the reported delays. My system packs 48GB RAM, so the OS has ample space to do whatever it needs to do without hampering any application (it's not yet fully used in case you're wondering 😉 ).
  
  Hoping that someone else will chime in.
