If you use the TMUI edit for ILX, the system will append a linefeed character every time you save. This is not usually apparent, but if you edit the file, then delete your changes, and then save it, it will still register as changed. A message indicates the need to refresh the workspace, and the actual content of the file will change, but not the functionality.


File contents can change unexpectedly and have needless characters at the end.


Edit a workspace file in ILX via the TMUI editor (i.e., the GUI).


Use TMSH or a different editor, that is not TMUI, to change those files.

Fix Information

TMUI no longer appends a linefeed character when saving.
