dialog help in ie6/7 badly needed


So I'm using the dialog UI element and it works great. I have a few
problems most gravely in IE6 / 7. One dialog that I open has
transparent (completely) title bar and button area. Also it included a
simple for w/ one text field. That shows up only the first time I load
it then it dissapears on subsequent loads. I am destroying the dialogs
after each closing because if I don't opening the main dialog (to sign
up for a newsletter) after awhile it positions itself in strange
places on the screen despite it's position being set to
'middle' (actually ['middle', 'middle'] doesn't seem to make a diff
either way.
The crazy thing is that if a valid email address is not entered I open
up another dialog to inform the user of this. This works fine and
displays fine. Also, I use on other pages a dialog and that works
fine.
Here's the IE6 pic of the first dialog (this is after the text are
field dissapears).

And the second which only opens on top of the first

I'm not sure if this is a CSS framework issue, a JS issue, or just the
usual IE is shite issue. But any help would be much appreciated.
IE7 to follow shortly after I switch VM's.
