Hmmm.....does anyone else work with a large amount of photos and notice some really slow operation of Lightroom? i'm importing old stuff and am up to 63,000 photos or so. When it starts up it takes about 5 minutes for it to be responsive and I notice all the image counts go from what they are to 0 and then it does some form of checking before it pops those numbers back up. In that time, it starts at about 160MB of RAM used and then slowly works up to 400MB or so. I have purchased more RAM because if you use Lightroom and open Photoshop, you're quickly over 1GB of RAM in use.
Otherwise, it goes along fine for a while, I can scroll through images I've already previewed and then it'll just pause for 20 seconds while it does...???? It's kinda annoying. If the additional RAM doesn't help (I have 1GB of PC3200 HT in two 512 sticks and am buying two additional 1GB sticks) I might be going back to the old way. While things like removing spots will take longer, 90% of the work I do will take far less time as I'm not waiting for the system.
Other than that, I still have a Export issue to bring up with tech support. Most likely it's something with my burner drivers.
