I've had an annoying issue where full-screen apps (e.g. pressing F5 in powerpoint) show the Mac Dashboard for no reason and then close it again. I've updated to Windows 8 and now most apps in Coherence (reader, messages etc.) show as fullscreen. I've noticed that if you go to Settings->Mission Control and untick 'Show Dashboard as a space' this issue goes away. Hope this helps out someone else!
nope Yeah that didn't work, it still does it. Pretty annoying too. Has anyone else managed to fix this? If I put Parallels in Non-Coherence and run as full screen I don't get any issues but in coherence it still has problems and shows the dashboard in the background, takes the VM off focus and disallows me from giving presentations.
