I can confirm this behaviour. If all you have on a line is spaces pressing Backspace with the cursor at the end of the line removes all the spaces.
OK just had a play and it's down to the Smart Tabs option. If you have it enabled then this behaviour happens but if you disable it then it deletes a number of spaces based upon the number you have set for tab width. -- Carbonize <http://forum.pspad.com/read.php?2,56268,56273> PSPad freeware editor http://www.pspad.com
