This functionality is supported only if you are using the Classic Agent.
If you are recording against a Web page that contains DHTML popup menus or other elements with JavaScript mouse movement event handlers, such as onmouseover, many MoveMouse() calls are generated. The MoveMouse() calls are recorded in order to improve reliability of playback against DHTML popup menus by ensuring that Silk Test Classic exposes the menus as it navigates through them. This behavior was added in Silk Test 7.1 as a replacement for the previous requirement of holding down the Shift key while recording against DHTML popup menus, since that requirement would not have been easily known to users. There is no straightforward way for Silk Test Classic to know whether or not a mouse movement event handler belongs to an element, such as a popup menu, that requires exposure. Therefore a MoveMouse() is recorded for any such element to ensure that the event handlers are triggered during playback.
There is no setting that directs the Recorder to exclude the MoveMouse() calls. The extra calls should not cause problems or slow playback, but you can manually delete the calls from the scripts, as long as the target elements do not require exposure.
