Paul: I found SDBG.ini in the Windows System folder, if I erase, you said would be safe. Will it be restored when I again use PLATO or SDBG, Sid Kraft

Yes. It contains your data such as the saved position of the various windows. If your main window has ended up off screen then you won't be able to see it. Deleting sdbg.ini will revert to the defaults - as it was before first installation.

Paul: Saved sbdg.ini in a file, deleted it from windows, tried to run sdbg again from command prompt and also Plato, would not start, are you sure it can be deleted and will automatically be re-created at startup of sbdg? Good thing that I saved in another file so I could then copy back into the Windows file. Sid Kraft

Perhaps there is a different problem with your computer set up. If you had an older version of Windows and FTN95 on it, there could be an SDBG.INI in the Windows system directory. If you then installed Windows 10, the location for SDBG.INI got changed to a subdirectory of C:\Users\username\AppData.

If so, changing the old SDBG.INI in the system directory is not going to help. You have to look in the new location and fix/delete that newer copy of SDBG.INI. The dates of those files should help you to decide which is old and which is new.

sdbg.ini is not shipped/installed with FTN95 etc. so sdbg.exe has to default to running without it. It contains user data that can be ignored. The file does not exist in the initial setup. Try installing FTN95 etc. on a virgin machine and check for yourself.
