Likewise I agree with Allen you should not be seeing errors due to CSS.
There are a few new classes defined but they would not be called for in 6.1 but would not produce errors. The main difference between the CSS files in Threads is compliance from CSS 1 to CSS 2. Big change was you should see something like this in a 6.1 stylesheet
body {
background: #80e4ff;
}
That would pass a CSS version 1 test
In 6.2 which validates CSS version 2 you see this
body {
color: #000000;
background: #80e4ff;
font-family: Verdana, Arial, Helvetica, sans-serif;
font-size: 9pt;
}
All your doing is defining every variable and not leaving anything to guess. If anything you are leaving less room for error.
