I haven't been using
levels but I tried it with several pictures and got ok results. The one thing I did find is that I had to hit the reset button on the levels menu (right above the eye droppers). Otherwise it seems to try to use the "last used" and gives random results.
I've been using PSP X3 since it first came out and have been pleased with it. Although I have been looking at CS5 with its context sensitive object replace. I'm hoping Corel will put something like that in PSP Xnext. The object remover and smart carver work pretty good but ....
Let me know if the reset button helps. We PSPrs need to hang together
