We are having users report lots of problems with cursor position and expected behavior in the new editor. Not all have clear steps to reproduce, but here's an example that I can replicate:
1) (IE 8 and Firefox 8 at least) Table navigation doesn't work within a list - Create a page. Start a numbered list. Type foo for the first item and bar for the second. Now insert a small table in the second item (common in say, instructions). Type in the first table cell. Hit TAB. Expected behavior is to tab to the next table cell, but instead the list item just indents further. You also cannot hit tab to add a new table line the way you normally do with a table.
2) Using bold within a list causes cursor to get stuck/lost (Chrome 15, partially broken in IE8) - Start a bulleted list. Type foo and hit Enter. On the second item hit TAB to indent, click the Bold icon and type bar. Click the Bold icon again to turn off bold. Hit Enter twice more and then type hello. On Chrome, the cursor freezes/disappears. On IE8, the second Enter causes the list item to outdent back to the first level, and when you type the h in hello, the bullet disappears. On FF8 it works ok.
These are a couple of examples ... but overall people seem to be having problems typing more complex wiki pages now, especially with lists involved. I have also had other cases (usually I use FF8) where the cursor seems to get lost.
