Hello. There is time when the selection of the grid is not drawn normally.  (1), I let a grid scroll
(2), I choose a one cell
(3), I choose the cell of the last line while pushing shift.
A selection is not drawn normally The test environment is Prof2.85 (2009-01-14). http://ifreeta.dee.cc/20090324/SampleMuGrid200903a.lzh
