Yes, Coherence Mode does not work correct, don´t pull the trigger, wait for the new release (of course to buy) or switch to another product. I change to VMWARE Fusion 5.
I've lost Internet access in Windows 7 since upgrading to 10.8.1. Tried all the different networking options, reinstalled Parallels Tools, reinstalled Parallels, reinstalled the 10.8.1 upgrade - nothing helps!
