I've noticed since downloading 1.5, build 740, that just by opening Netscape causes my download speeds to sometimes more than double. But if you surf to a site that has a busy screen, it'll slow down. Try to surf to sites that don't have alot of movement or cookies attached. After a while, no matter where you go, xolox will start to slow down anyway. Close your browser, and speeds go up again for a few minutes. When you see things slowing down again, reopen the browser and repeat. This also works when I tell my mail program to download new messages. Further, if I'm not getting any search results, I open the browser , look at a simple page or two, and when I go back to xolox, I have search results! I'm using a dial-up connection, so this probably has some bearing on this phenomenon. I also post this as a possible hint to the folks at xolox to help improve the product.
Anyone else notice this?

The new version(1.56) solves ALL the problems I had seen. Currently getting 9 peers, and search results are flying in so fast, my connection(cable modem) feels a bit sluggish. This release fixes the connection to Limewire issue that was causing problems for the past few weeks as well.

Great job Xolox development team!
