When adding attachments to an email, the window becomes split, and the attachments appear in a very small separate window at the bottom, suitable for just a few attachments, depending upon your window resolution. If you add more than 4-6 attachments, a scroll bar appears, but the window splitter doesn't expand, nor can I adjust the window splitter manually. The attachment area is tiny, as is the scroll bar. Have you considered re-designing that function?
