Don''t know whether this is Lafite not setting EXTENTs right, or something in Lisp.  '
'
When the absolute last message in a folder is selected, and its 1-line header is at the bottom of the browser, the scrollbar leaves a significant amount of space between its shaded area and the bottom of the scrollbar region.  When the shaded area "sits" at the bottom of the scrollbar, then the last 1-line header is in the middle of the window.'
'
For the record, some other systems have the following amount of space left at the bottom of the window when the shaded area "sits" at the bottom':'

I assume this is some sort of rounding error in the display code.  Lafite is doing the right thing--the BOTTOM of its EXTENT and the BOTTOM of its clipping region are identical when the last message is at the bottom of the browser.'
