Selfishly, I wish it were only a Windows problem, but alas, MacPro, 16GB Ram, 8TB of external disc space, (but no Nvidia CUDA graphics card, yet), and I have some files (from last year) which have lots of effects and the project file is in the reasonable 6.5MB size, but now they're bloating out to 580MB. Analyzing current project, the project manager is taking ages to load;
There are so many variables we're all working with different plug-ins and computers and projects, so getting one or two answers that will solve it for each of us is probably impossible. I use Colorista II but I dumped Looks because it was giving me major freezes and other weird behaviour; sure, I have effects, some wipes, some fades, the usual, it doesn't have more than a couple of AE clips, and five minutes after I began writing this the "analyzing project...." window still doesn't even have the beginnings of a progress bar.
