Troubleshooting - Drop-down List Box Options not visible

In certain instances the drop-down list box options in K2 Studio screens are displayed behind the main window.  The drop-down list is unable to be displayed correctly and no values can be selected.  In some cases no options will be displayed, but in some instances only a few options are displayed behind the main window.

Solution:

This error occurs due to Win32k.sys driver displaying the order of layered windows incorrectly.  For a work around see http://help.k2.com/en/KB000251.aspx
