31.49 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:
Go to Window > Preferences.
From here go to: General > Appearance > Colors and Fonts.
In the window on the right side choose: e Language > Editor > e Language Text Font
Press Edit and check that the font you are using is monospaced. If it isn't, choose one from the list ( ex: Courier, Monospace).
Ok > Apply
