If you are in the case that your mouse is not working correctly in your VMware Virtual Machine, it is due to the conflict happened between Microsoft VM mouse driver and VMware VM mouse driver.

Resolution
========
1. Go to regedit and find out the key below:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E96F-E325-11CE-BFC1-08002BE10318}

2. Remove the value msvmmouf from the UpperFilters Regvalue.

And then reboot your OS.

Good luck
