I wrote a similar thread before but had no answer, now I have even more problems. I upgraded to the latest nightly build (01.19) but it has the same problems. The main problem is that in IE or Maxthon I can't see the scroll bar in the admin field but it works in Firefox. Now I noticed that my new post look ok but the older (before 2.0) post have bigger letters in IE. In Firefox it is allright. here is the previous thread: http://wordpress.org/support/topic/53618
you can check my blog and see for yourselves: http://stadi.atw.hu (it's in Hungarian)
I'll try to upload screenshots from the admin sometimes later.
