I'm running Win 7 x64 boot camp install as a VM using PD4, OSX Leopard. I'm having pretty terrible performance, with a lot of locking up while doing even basic tasks such as browsing the web. Looking through here, I've found that PD4 performance is poor at best with Windows 7, and locking up has been reported by many. Have these problems been resolved from in PD5? scanning these forums I get the impression that they have, but at the expense of sound and other issues...
