I assume you are talking about the controls listed in the "ActiveX" tab of the Object browse (which are built by some other applications and shared with Lookout through ActiveX). There are two sections of these controls, "Recommended" which our R&D group has tested and know to work, and "Other" which may or may not work perfectly. Which category does your control of interest fall under? Generally speaking, the "Other" might be less functional (simply because they aren't known to work with Lookout). Also, when configuring the behavior of controls, sometimes it's hit or miss whether the ActiveX control can do exactly what you want. Lookout is intended to be as open as possible by utilizing ActiveX technology, but the particular control must have the proper parameters to be configured in the first place.
