How to sync mouse pointer correctly in screen sharing when connecting to a Windows VM? I am using the screen sharing application on a MacBook Air running OS X 10.9.3 to connect to a Windows 7 virtual machine on a different computer.

Although the keyboard and mouse work in general (input is received by the VM), the mouse pointer is not synced correctly. I see two mouse pointers: the Windows one and the one from my Mac. However, the Windows mouse pointer is always off by quite a bit. It seems to have a higher acceleration. If I quickly move my mouse, the Windows mouse pointers moves more than my Mac's.

I cannot find any information on the Web about this problem. Is this a known issue? Should it work with Windows systems?
In the Screen Sharing app, go to the View menu and click "Customize Toolbar..." There's a button you can add to the toolbar called "Cursor" that toggles your Mac's mouse cursor. You can turn it off so you'll only see the one on the remote machine instead of both the remote and local cursor.
