Serious problem with "Spaces" since #6.0.11994

Hi,
i've configured Parallels to start in Space 2 (out of 2). The guest OS (Win7 x86 SP1) starts directly. So while starting Parallels, MacOS changes automatically to Space 2 and i'm seeing the lunching procedure. But when i try to switch back to Space 1 (ctrl+1) during the Guest OS starts it's getting problematic:
1. The VM changes it's position automatically from Space 2 to 1
2. The lamp in the start dock, which indicates that Paralells is started disappears, in addition i have no access to the menus (settings, view, update...)

Now while lunching the VM i have to wait until windows is up. This problem didn't exists in #6.0.11992 and before!

Happy Easter
