I am using Mplus on the ITS Windows Terminal Server (WTS). When I open an Mplus command file and run it, it works fine. When I use Save As in the File menu to save the command file under a different file name, Mplus doesn't work. What is wrong?
Mplus was not specifically written for the Windows terminal server environment, so several oddities can arise when you use it in this environment. One unusual feature is that if you save a previously working Mplus command file, you must exit Mplus and relaunch it. Then your saved file should work correctly. Note that you can modify an existing command file within Mplus without exiting the program.
Also, you should be sure to save each command file before you run it through Mplus's command interpreter (i.e., save your command file before you run your model). Mplus writes its output information to the user's window by default; if you want to reaccess your original command file you must open it again by using the File menu and selecting the Open option or the list of the four most recently-accessed files located at the bottom of the File menu.
