Throttle layout files can consist of a single throttle window (to control a single locomotive or consist address), or it can contain multiple throttle windows. In either case, when opening a throttle layout file, the program will check to see if any existing active throttle windows are already open. If none are found, then the file is opened just like a simple layout opening (explained above).

Figure 4-5: Merge Dialog Box
However, when one or more throttle windows are discovered already open on the screen, the program will open up a dialog box as shown in figure 4-5 on the right.
- Merge — leaves the currently active open throttle
windows in place and opens the throttle(s) contained in the layout file
being opened.
- Replace — closes down the currently active open
throttle window(s) and opens up the throttle window(s) established in the
saved layout file.
- Cancel — cancels the "open" request and closes down this dialog window.
Note: Do not confuse the action that is occurring here with any attempts to overwrite your saved throttle layout files. The above actions have no effect on the actual saved throttle layout files themselves. The only "merging" and "replacing" that occurs is simply on your screen.
