Stupid Question

[Morpheusdead]

And probably asked before but....
I have noticed that if I open an xml in wordpad it looks much neater than in notepad but........... even if i dont change a thing but just save it it will totally screw the code ??? I had to find this out the hard way after many times of having to do the whole code all over again when it was working to begin with LOL can anyone explain to me why wordpad does this?

or maybe its some setting in my version of wordpad?
