When adding attachments to an email that I am composing, the attachment pane at the bottom of the window shows there are attachments and the size, but I cannot view the list of attachments, say to verify what I attached or delete an attachment. Clicking on the bar toggles the caret from > to v but does not show the list. I have also tried to resize the pane and the double arrow appears and can be dragged, but the pane does not resize. I have also tried selecting and deselecting the "Attachment Pane" option form the View Menu, without success. I have attached a screen shot. Any help would be appreciated.
