Not sure, but it may be a bug.
The problem is that I can't set the position of the "Code editor". What I do is move the window to the position, open Tools > Configuration... > Window, select the "Code editor", press "Get position" then "Apply" and "Accept". But everytime I open Lazarus the window isn't in the right position. This is specially annoying since I use two monitors and it moves the editor to the wrong one (sometimes I have that monitor off). I've tested also the radio buttons (they're in Spanish, I don't know the text in English) but no-one seems to put the window where I need.
Suggestions?
