Things that are supposed to be fixed in ie 7 include:

Peekaboo bug

Guillotine bug

Duplicate Character bug

Border Chaos

No Scroll bug

3 Pixel Text Jog

Magic Creeping Text bug

Bottom Margin bug on Hover

Losing the ability to highlight text under the top border

IE/Win Line-height bug

Double Float Margin Bug

Quirky Percentages in IE

Duplicate indent

Moving viewport scrollbar outside HTML borders

If it all is included in the final version, ie 7 will be a blessing to us ( web developing grunts )…
