I am having an interesting problem in the new message compossition screen. After I upgraded to 7.4 yesterday I started getting complaints that some of my users couldn't attach anything to their emails because they could not find the attach button at the bottom of the screen anymore. After some investigation I found that all of the users with the problem were using Internet Explorer (IE5 or IE7) and that the status bar was covering a portion of the screen, including the bottom arrow of the scroll bar, blocking the attachment stuff. The other browsers I tried (Firefox 2, Firefox 3, Google Chrome) don't have this problem.
Any Ideas on how I can go about fixing this?
