This is problematic for writing applications that require keyboard input, such as games or other interactive application software, since it is impossible to distinguish an actual key event from a repeated key event. For example, in Internet Explorer and Firefox under Windows, key repeat usually triggers both the JavaScript keydown and keypress events, but not keyup. This way, it is relatively easy to filter out keydown events, since they are not followed by a keyup. However, under Virtualbox, key repeat triggers keypress, keydown AND keyup events. To immediately witness the effect, please try keyboard scrolling Google Maps with Firefox or IE in a Windows guest and a Linux host. You can also try the attached HTML file which contains reproduction code. Thank you for the wonderful VirtualBox software, and I hope I can make it better this way!
