    Hi,
    I am working with Mac OSX 10.12 and Parallels Desktop 12.0.2 with Windows 10 (clean install) on a MacBook Pro 16GB RAM and dual monitors.
    I can start the windows 10 session and work for a while with 3 (quite large) Excel files in coherence mode, but after a while the screen update does not work anymore, the screen is partially updated, get completely white or black and the only way is to quit everything (without a way to now really is work in progress is saved) and restart Windows. Switching off coherence does not help.
    Does anyone has solution to this problem ?
    Thank you in advance
