I hope they fix the memory issues I'm running into with the Beta. With just a handful of 11MB RAW files in the library, I very rapidly build up memory usage while developing. When it gets above 1GB of memory use I get out-of-memory errors on my 4GB 32-bit Win7 laptop. I have to close LR and restart it to continue (until the next lockup).
