In the default 0.6.0 classic template, under IE6, the 
space between the boxes (Issues, Hello XX, Help etc) 
varies depending on whether they're a form or a para.

To tidy this up, I added a styling for form to my 
style.css:

td.sidebar form {
  margin: 0 0 0 0;
}

so that the only margin between these boxes is the 
p.classblock/p.userblock margin.

(I also found it looked slightly less cramped with 
p.classblock and p.userblock set to:
  padding: 2 5 2 5;
  margin: 5 1 5 1;
but maybe that's just me.)

Logged In: YES 
user_id=6405

accepted (except that last margin bit - it is just you :)
