View > Dive
Opens the selected process or thread in a Process Window. If the process already owns a Process Window, that window is moved to the front of the display. If a Process Window does not exist, TotalView creates a window for it or replaces the contents in an existing window. Note that TotalView tries very hard to reuse Process Window.
If a Process Window already exists, the window is focused on an arbitrary thread. If the process has no open windows, TotalView opens a window containing the first thread in the process.
If you want the dive operation to create a new window, use the
View > Dive in New Window command
