With Parallels 4, I used to be able to click a number of icons on my dock, including Parallels (which was suspended--Windows XP) and a number of icons for programs within Parallels. In Parallels 4, this would open Parallels, and the various programs whose icons I clicked would open.
With Parallels 5, when I do the same, Parallels will bring Windows back from suspend, and the little white circles will appear under the program icons in the dock, but the programs don't open.
I've upgraded to the latest build of Parallels (5.0.9308), and I've reduced the amount of RAM allocated to the guest OS (reduced from 1024 to 768 MB out of 2GB physical memory), but the problem still happens.
Between the slower resume and my programs not opening from the dock, I'm seriously considering reverting to Parallels 4. I am not impressed with 5.
