When I edit anything with notepad.exe or wordpad.exe (Win Vista) all my formatting is lost when I reopen it.

For example, I wanted to edit my .htaccess file so I start with:
Quote
RewriteEngine On
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://(www\.)?mysite.com/.*$ [NC]
RewriteRule \.(js|pdf|css)$ - [F]

RewriteCond %{HTTP_REFERER} iaea\.org [OR]
RewriteCond %{HTTP_USER_AGENT} Baiduspider [OR]
RewriteCond %{HTTP_USER_AGENT} BecomeBot [OR]
RewriteCond %{HTTP_USER_AGENT} BecomeJPBot [OR]
RewriteCond %{HTTP_USER_AGENT} BilgiBot [OR]
RewriteCond %{HTTP_USER_AGENT} Bot [OR]
RewriteCond %{HTTP_USER_AGENT} ContactBot [OR]
RewriteCond %{HTTP_USER_AGENT} EmailSiphon [OR]
RewriteCond %{HTTP_USER_AGENT} Gaisbot [OR]
RewriteCond %{HTTP_USER_AGENT} ichiro [OR]
RewriteCond %{HTTP_USER_AGENT} "Indy Library" [OR]
RewriteCond %{HTTP_USER_AGENT} IRLbot [OR]
RewriteCond %{HTTP_USER_AGENT} libwww-perl [OR]
RewriteCond %{HTTP_USER_AGENT} LinkWalker [OR]
RewriteCond %{HTTP_USER_AGENT} MJ12bot [OR]
RewriteCond %{HTTP_USER_AGENT} my-heritrix-crawler [OR]
RewriteCond %{HTTP_USER_AGENT} Psbot [OR]
RewriteCond %{HTTP_USER_AGENT} PlantyNet_WebRobot [OR]
RewriteCond %{HTTP_USER_AGENT} RobSoft [OR]
RewriteCond %{HTTP_USER_AGENT} SBIder [OR]
RewriteCond %{HTTP_USER_AGENT} shelob [OR]
RewriteCond %{HTTP_USER_AGENT} sohu-search [OR]
RewriteCond %{HTTP_USER_AGENT} sogou [OR]
RewriteCond %{HTTP_USER_AGENT} sogou-spider [OR]
RewriteCond %{HTTP_USER_AGENT} sogou-web-spider [OR]
RewriteCond %{HTTP_USER_AGENT} Twiceler [OR]
RewriteCond %{HTTP_USER_AGENT} wwwster [OR]
RewriteCond %{HTTP_USER_AGENT} Y!J-SRD [OR]
RewriteCond %{HTTP_USER_AGENT} "Yahoo! Slurp China" [OR]
RewriteCond %{HTTP_USER_AGENT} Yandex [OR]
RewriteCond %{HTTP_USER_AGENT} Yeti
RewriteRule .* - [F,L]

order allow,deny
deny from 64.92.199 #thenewpush
allow from all

Then I save it and when I reopen it again I get this:
Quote

EVERY FLAMIN' TIME! mad

What can I edit my .php, .htaccess, .txt, .cgi, etc. files with so it keeps the formatting?
