Same here. 4.1 is awfully slow. I thought it was just me. Back to 4 beta now.
The new beta works fine for me. I guess it all depends on your hardware's configuration.
Yep, works like a charm. In fact, starting up is way faster. My primary machine is a PowerBook G4 with a mere 1GHz CPU speed and 1GB of RAM.
In fact, when run on my office laptop, which is an Acer with 1.67GHz Core Duo and 1GB RAM, Lightroom just flies.
Then why is it so **** on my 3ghz dual core with 1GB RAM?
