    I have recently purchased Parallels Desktop 12, and I am using it with a Win XP Pro guest OS and MacOS Sierra host OS.

    All seems to work well, except for one problem with the mouse wheel scrolling. If I scroll the contents of a Windows folder (eg. set to list view), the movement is far too much, to the extent that some of the columns are missed completely. Changing the number of lines per wheel click in the Windows mouse control panel makes no difference. What could be causing this, and is there a solution ?

    I have tried using the same guest OS under VMWare Fusion, and that doesn't exhibit the same issue, so it isn't a Windows bug.

    Hi @ChrisS6, please follow the steps suggested below:
    1. Open virtual machine's configuration: -> Hardware tab -> Mouse & Keyboard -> set SmartMouse to Optimize for games. Do not close configuration window.
    2. Set desire mouse sensitivity in Windows virtual machine: Control Panel -> Mouse Properties -> Pointer Options tab -> Select a pointer speed
    3. Get back to virtual machine's configuration window. Set SmartMouse to Auto-detect for games.

    If the issue persists, please do the following steps to resolve the issue:
    1. Shut down the virtual machine.
    2. Switch to Hardware tab > Graphics > Extend Advanced Settings.
    3. Make sure that vertical synchronization is enabled.
    4. Start the virtual machine and it should be good.

    Hi Paul,
    Thanks for your reply.
    I tried both of the procedures you described, but there was no change. Vertical sync was already enabled.
    Note that this is the mouse wheel, not the pointer which has the problem.
    Chris.

    It is very disappointing that there is apparently no solution to this, as it makes Parallels pretty much unusable. For example, when navigating within an application for a file, you can't actually use the scroll wheel because whole rafts of files are bypassed with each wheel click. Somehow, Parallels breaks the mouse driver. Worse still, I paid for this product, so it's money down the drain.

    Back to VMWare which behaves perfectly (albeit a bit slower).

    Hi @ChrisS6 we are sorry that you're unhappy with the Parallels Desktop, but if you would like to continue investigation please provide us with the following info:
    Do you have this issue with all Windows apps or with the specific one?

    It happens in all Windows apps and within any open Windows folder on the desktop. Changing the wheels settings in the Mouse control panel doesn't do anything.

    Please try to reinstall mouse drivers in device manager:

    Device manager -> Mice and other pointing device -> right lick on Parallels mouse synchronization device and choose "scan for hardware changes"

    That has absolutely no effect.

    I have logged a problem report, and I posted the report number here yesterday. Unfortunately my post has disappeared.
    How do I find my report number, as there was no email confirmation of the report being logged ?
