Hello, Versions: Windows 10, 1703/Build 15063.296. MacOS Sierra, 10.12.5, Parallels Pro 12.2.0 (41591). Lost ability today to get mouse clicks to work in the WIndows 10/Parallels VM. Mouse movement/trails work within Windows 10 window, but I cannot engage any icon, menu, focus, etc. left or right button. I was using a standard Logitech Bluetooth (dongle) type mouse, but also connected a USB wired mouse. Again, both mouses work just fine on the Apple OS, movement/clicks. I have tried in Parallels Host OS Configuration/Hardware: 1. Reset Mouse: Optimize for games, Don't Optimize from Games -- no change 2. REmove and re-add USB/Bluetooth -- no change 3. Remove and reinstall Parallels tools -- no change I am continuing to try different things. Any other ideas you have or is this a known problem?
