Version pgadmin-III 1.8.4.
Operating System Windows 2000 RussianWin1251

Errors:
1. I am seting mode [CLRF Dos] in "Sql editor", text is coverting Ok. 
But when am starting to type new text, new text is inputing with [LF] 
symbol.
2. When I open new work session on "Sql editor", setting [CLRF Dos] 
reset on [LF]. :(     Need save this setting in options menu. My Cvs 
system not made compare when .sql include [LF] in text file :(

I want New Enhancements:
