I'm not sure if it's even related...so I may post a new thread if you advise me to do so. However I have a prl_vm_app process consuming 100-150% CPU on a Dual Core Dual Processor Mac Pro. I have otherwise had no issues but the rogue prl_vm_app process cannot be killed. I'm running 5.0.9344.558741. My host OS is 10.6.2 fully patched. Guest OS is WinXP SP3 fully patched. Any ideas?
