In the Workstation Pro preferences there is a checkbox "Automatically grab and ungrab the mouse". Unchecking that probably has the desired effect that you are looking for

Since Player does not have that checkbox, go to %APPDATA%\VMware\preferences.ini file, add or change the following lines

pref.motionGrab = "FALSE"
pref.motionUngrab = "FALSE"

As it is in the preferences, it affects all VMs.
