Lines are suddenly changing indentation when I edit text or move the cursor through the editor.

This might happen if you don’t use a monospaced font ( e.g: Courier ). To change the editor font:

1. Go to Window > Preferences.

2. From here, go to General > Appearance > Colors and Fonts.

3. In the window on the right side choose: PSS Language > Editor > PSS Language Text Font.

4. Press Edit and check that the font you are using is monospaced. If it isn’t, choose one from the list ( ex: Courier, Monospace).

5. Ok > Apply
