IE8 and IE7 have a zoom tool in the bottom right corner of the browser window. If this is set at anything other 100% Certify will pass input steps without finding the desired objects resulting in a false positive. Be sure the browser is not zoomed in or out before executing tests with Certify. This applies to both the HTML (Web) Interface and the SAP WEBgui Interface.
To ensure this is always set correctly, add a step to your Launch Browser process to send keys "^0" to the ActiveWindow this key combination (Ctrl+0) sets the zoom level to 100% and will pass even if the browser is already at 100%.
