I don't understand...certain applications (such as WoW at the moment) will not install. When I double click the installers, the icon grows as if it's going to execute...yet nothing happens. This has also happened on the Windows Media Player for OS X and on a screen saver I've tried installing. Any ideas what the deal is with this? Or is it that it's trying to execute power-pc code? The thing is, I've installed WoW on intel-based macs before and did not have this problem...
