How do I get backslashes to save? Everytime that I type a backslash into a textbox on my drupal site (in content editors, administration pages, you name it; I mean any textbox), it gets filtered out before it reaches the module code. 

So I end up typing something like this:


  This is just some content with an \n
  or a directory structure like
  C:\Program Files\whatever


And it gets converted to this on save:


  This is just some content with an n
  or a directory structure like
  C:Program Fileswhatever


This really makes it hard to edit content on my D6 site; anyone know a fix for this?

This is on admin pages; so filters aren't used.
This sounds like it may be a magic_quotes issue. If at all possible, disable this in your PHP configuration. Instructions on how to disable them are on the PHP website. If this is enabled on a live, shared server and you don't have access to the PHP configuration then I would highly recommend looking for a new host. The magic_quotes_gpc option has been deprecated in PHP 5.3, and will likely be removed very soon.

Magic quotes provide a way of escaping incoming input, and have been frowned on for quite a while in favor of validating input properly in your application, which Drupal does.
