virtualbox.org

When I do mouse drag inside the guest operation system window, the guest window will be resized. once bigger, once smaller, over and over again. This also happens when I do double click. Why?!

Version: 4.2.12 r84980
Host OS: Windows XP Pro with SP3
Guest OS: MSDOS6.22 / android-x86-4.3-20130725

I've never encountered this situation.
But you can update VirtualBox to the latest version.Maybe can deal with the problem.
