Mozilla 9.50 - lags like hell when i drag components in admin builder pages. Also can't add new block on empty Active area (new elem frame just don't popup).
IE 6.0 - some Block and Field rectangles got no rendering in some cases (working with builder) so i can't see them at all, but they're there definetly cuz i can still click them for options popup. Quiet laggy.
Can't click on subpages radio buttons, instead only clicks on text helps, for ex. for selecting: Simple, Quick, Advanced search.
Opera - omg, works fine by now. No lags, perfect insertion of elements...
And one more bug. I've managed to drag Field element called Nickname into Inactive area used by Block elements - wtf?
Then i can't use Nickname anymore, except forced page reload by browser functions.
