problem with switching views in OO version 2.x

[johnny]

After saving HTML code, I switch views from HTML source to Web layout then back to HTML source. When I do this, my script tag changes from <script type="text/javascript"> to <script>. This causes the code to fail the W3C validation test. I've noticed that all of the tags are changed to uppercase also. OO also adds other stuff (such as language values to the body tag) and modifies form action values to absolute path names. Why does the code change happen? Can this process be disabled?
