Internet explorer stops working

[robsch@yeoandyeo.com]

We have an issue with IE9 (Windows 7 64bit) and our Display link devices. Input screens in IE9 do not refresh or there is a 15+ second delay on monitors with the DisplayLink devices. For example, if you type in a google search, nothing appears in the box, but if you drag the window over to a different monitor the text instantly appears. If you leave it on the DisplayLink monitor, eventually the search come through. Many times when you drag an IE9 Window back to the Display link monitor there are trails of the Window on it. Fortunately we have tied the problem directly with the installation of a Windows Platform update KB2670838. If the update is uninstalled the problem goes away. The display link driver we are using is 5.6.31854.0.
