The guest mouse area becomes horizontaly restricted and the pointer incorrectly returns to the host (as if right ctrl key was pressed) when moved beyond the boundary. These boundaries change when the mouse is moved quickly. My guest OS is Tinycore. The mouse behaves correctly when the guest window is dragged back to the 1st monitor. This problem does not occur with VB 3.2.12 and earlier releases. I am not using guest additions. defect closed other VirtualBox 4.0.4 duplicate mouse dual monitor 4.0 Linux Windows
