[imp] IMP 4 RC1 problems.

[Steve Lidie]

1) Anytime a message is deleted, the display is repainted with an empty 
screen, except for the toolbar column on the left.  Selecting "Mail" 
brings me back to the INBOX.

2) Under Folders from the top toolbar, clicking on the plus sign to 
expand the INBOX fails.  The plus changes to a minus, and you can see 
the faint, vertical, dashed line that would connect the rest of the 
tree, but the frame doesn't expand, thus you cannot see anything.

These test were done using Safari on Mac OS X Panther, and XP Pro using 
Mozilla and IE.

On FireFox on the Mac, no icons appear in the Folders toolbar, rather, 
just plain text.
