Craig,

I plan to address this problem. I think what is happening is it is blanking
out the row and then because records need to be fetched in it is doing it
during the time the grid is painting. I am now making sure all rows are
fetched prior to the paint cycle so this shouldn't be an issue any longer.

I'll presume that you want on the v4 BETA so that you can be sure this is
properly taken care of.
