I am having an issue with WordPress 2.7 and Internet Explorer 8 Beta 2.
I'll be brief becuase I've posted the details at the link below this paragraph. Basically text in the content area in HTML view often does not wrap within the textarea, and in Visual view, text in the textarea (and text field of the title) both stop short when they change their width when you make your browser window wider. You can read the details and see what I mean here:
I belive it's an issue with Internet Explorer and not WordPress (as I've tried it with Firefox and it's OK), but I cannot seem to login and report it with Microsoft on their IE feedback site, and would appreciate it if someone could try to do it.
Basically, there is something similar already reported at the link below, but when I sign in to post feedback the page at this link says that I've accessed the page incorrectly (appears when not logged in but not when logged in).
