Hi Kirk
That sounds great, but what time zone are you in? I am in Perth Australia, +8GMT, so working hours for you is probably mainly sleeping hours for me - but there is likely some reasonable cross over period.
I will answer your questions below.
1) Images are stored on a separate drive internal drive (WD Caviar green, btw) from PM but all drives are in the same machine
2) Sort method is just all files, by filename. I do have different files tagged different colours, but it does not seem to matter and in any case I am not filtering them.
3) Creating new folders - just some background - we shoot high school graduations. Each school is a little different and when It comes time to ready their images for the website, I create new folders as needed by selecting the parent folder in the sidebar and control clicking it to reveal the "Create New Folder inside this folder" option the pop up menu.
4) Number of images in contact sheet varies from school to school, the one I am working on at the moment is 2700+ but the same issues were happening with a much smaller school, only 289 images.
It does not seem to be related to any one thing I am doing, as it does not matter what I am doing. Even if I go back to PM now, with only it and Safari open - I will get a spinning beach ball for about 35 seconds before I can access the program.
Cheers
Craig
PS, in the old days I would have said Trash the prefs, but there seems to be a number of them and I am not even sure if this is a valid option anymore.
