Host: Mac OSX Yosemite Guest: Windows 10 Configuration: Full screen, use all windows, require password to exit full screen When I click on a window other than the active window, there is a delay in which the click is not registered. When it finally is registered, it is as if the mouse was held down - any mouse movement causes whatever item you clicked to be moved. This is super troublesome when you click in to Outlook and accidentally drag your Inbox folder to the Deleted folder. If you clicked the window's titlebar, it will restore the window and move it.
Hello Redger, It is recommended to install Parallels Tools. The mouse Synchronization Tool enables mouse to seamlessly roll from virtual machine screen to primary OS and back without pressing a special hot key combination. Using this tool makes mouse movements smoother and improves system reaction on mouse.
