Macbook Pro 10.4.6 2.16 Ghz intel, 2 Gig SDRAM. Takes about 20 seconds for 4.4.3 to open a contact sheet of about 400 photos in one folder--Jpegs, total size about 1 gig. I know this is a big folder, and should probably be split up, but is this normal behaviour? The message at the bottom left of the page says "sort in progress" while the sheet is waiting to be opened. 4.4.2 seemed a lot faster.
