I've compiled 0AD in MacOSX 10.6 but am having serious errors assigning characters to tasks. Whenever I select a guy (or anything else you can move around and assign tasks to, but for the sake of the argument I'll just say "guy") and try to assign him to harvest metal, food, meat, attack, (or anything else other than "go here") my mouse pointer jumps to the center of the screen every time I mouse over something harvestable/attackable. This means, of course, that when I try to have him harvest a tree, my mouse jumps to the center of the screen, where the tree isn't. I was being attacked by an enemy ship and could not defend myself because the mouse would jump to the center of the screen every time I tried to have my ship attack the enemy. Any ideas? I am completely deficient regarding programming and geeky knowledge, so just compiling the program was a bit of a challenge for me, even though I had step-by-step instructions. Any help would be appreciated.
