Lightroom 4: slow and imprecise! I am very deceived by LR4 and I wish to have a refund. I purchased it basing on my experience with LR3 but what a bad surprise! The application is much slower than LR3, in particular the development tools are so slow that I couldn't work (I use correction tools quite a lot, which saves me from passing through PS). Add to that the fact that it changed all (all!) the curves of my previous edits and its inconsistency in tones and colors when editing in PS and it gives you the reason why I went back to LR3. And no, RC4.1 didn't solve the problems (it's a little less slow, but nothing making me consider to use it). Is it possible to have a refund?
