Hi, This is extremely frustrating and only seems to be happening with browser windows (firefox in particular), its random and cannot be reproduced on demand - although sometimes it will happen a lot and other times I may go for hours before it happens. I am running Parallels version 13.2.0. I have a Mac Pro (100GB RAM), 4 displays attached. Host OS is Windows 2012 R2, running in a custom developer mode (4 cores, 32 GB RAM, 1024 video RAM) What I am seeing is that when running in coherence mode; host browser windows when performing heavy operations (running JavaScript), will indiscriminately disappear from view (goes invisible, because it hasn't been pushed to the back). I think it only happens if there are Mac OS windows or other VM windows behind. Sometimes if I wait a while they reappear on their own, but more often than not I have to click on the browser in the task bar (which effectively minimizes it) and then click on it again to bring it back. The first click makes it reappear - but obviously it minimizes. Often this happens when doing a client demo, which as you can imagine is frustrating! I often run multiple VMs at the same time - although this issue happens when running a single or multiple VMs. Any thoughts or help would be much appreciated. Thanks, James.
