I downloaded Monogame version 113 and have to say I like it better than the New years version. Was enjoying Mullens pass running the LAUMIS west activity. everything was fine until I had to cut the helpers out at Ellison Found out That I could change the switch to put the helpers in the hole But the derail refused to change.

I think you'll need to use the Map Window-Dispatcher Tab for the derail

From the manual:

Quote

7.5 Map Window
Use the map window to monitor and control train operation. The Map window option must be selected
prior to starting the simulation.
The map window is opened and closed by pressing <Ctrl+9>. After the map window has been selected
with <Alt+Tab>, successive Alt+Tabs will toggle between the OR window and the dispatcher window.
The map window contains 2 tabs: Dispatcher and Timetable. Both provide maps of the route with each
train following its own path.
The map window is resizable and can also be maximized, e.g. on a second display.
To pan, use the left mouse button to drag the map around.
To zoom, use left and right mouse buttons together and drag vertically or use the mouse wheel.
To zoom in centred on a location, press Shift and click the left mouse button at that location.
To zoom out from a location, press Alt and click the left mouse button.
To zoom out fully, press Ctrl and click the left mouse button.
7.5.1 Dispatcher Tab

It could also require using the switch window (F8) to open the derail. Trailing point switches can no longer be operated by the G or Shift-G keys. This change makes sense, but has resulted in me hitting a couple derails on my routes that I had forgotten to mark

I've found that I have to use alt + the mouse for some time now.
