Refreshing a Scan
You can refresh a scan by hitting F5 or selecting Refresh from the Refresh Menu. The Empty Working Set menu item in the Refresh menu releases all physical memory assigned to the process and then refreshes the scan. This feature is useful for measuring the memory cost of an application feature where you would empty the working set, exercise the feature and then refresh the display to look at how much physical memory the application referenced.
VMMap saves every snapshot and you can view the history in the Timeline dialog. Select a particular snapshot by left-clicking in the graph area and moving the mouse to the desired snapshot point.
