Coherence not working after latest update - Parallels 11

Mac Book Air. Early 2015. 4GB RAM. MacOS 10.10.5 with Parallels 11 running Windows 10 and Ubuntu 14.4 VMs. These have have been working happily with Parallels 11 but I updated yesterday to the latest version. Since then coherence no longer works properly. I can see the VM thumbprints and I get various parts displayed correctly, like the Windows 10 start menu displayed properly but on top of the Mac display. Things like Skype appear on the Mac taskbar and when I click on them they appear properly displayed but again over the Mac background. So if I have the start menu displayed then click on Skype then the start menu disappears and Skype appears properly, but still over the Mac display. If I come out of coherence mode then I get everything displayed properly but in a smaller screen. It's exactly the same in Ubuntu. The VMs both operate properly.

Yes, I have already re-installed Parallel Tools but it has no effect. Very confusing. I have a Macbook Pro running Parallels 11 as well. I did have a similar problem in Windows 8 when I first loaded Parallels 11 but removing the Parallels video driver and re-installing Parallel Tools fixed it.

I did submit a report on this. Any ideas?

Any issue on Coherence does point to one major reason mostly: Parallels Tools not installed correctly.

Please follow the steps beloe and check:
- Take a snapshot(as a back-up)
- Uninstall Parallels Tools
- Uninstall Anti-virus program (if any)
- Check and install Windows updates
- Install Parallels Tools
