I have installed Windows 8.1 on VirtualBox on Ubuntu 14.04.
It works, however I have a problem with the mouse-integration feature of the guest additions (4.3.24).
Whenever, the pointer transforms into a cursor I get a big black ugly graphics-error style box around the cursor, making it practically unusable. It works fine except when hovering over textfields. What is the remedy to this ugly mouse-pointer error?
If I turn of mouse-integration it works, however the mouse is too slow and I have to press right-controll all the time to switch, which is really annoying.
