Hello! This bug we can see when we use "Trim trailing spaces" (Program settings -> Editor (part 1)) and "Real tabs" (Program settings -> Editor (part 2)) together.
Create a new file, press the button "Show/hide spaces, tabs & line ends" on the toolbar. Then press keys [A], [Tab] and [B]. We expect a real tab between "a" and "b", don't we? But instead a tab we see a sequence of spaces. If we will turn "Trim trailing spaces" off, everything will be OK - we will see a tab between "a" and "b". This problem moves from version to version and I hope that finally it will be corrected. -- <http://forum.pspad.com/read.php?4,68427,68427> PSPad freeware editor http://www.pspad.com
