Michel,

FYI, I got that same message from a different cause in EnThbnFm.DrawGridDrawCell.DrawStretched. It was from

FResizeTransform.Height

being set to zero in SafeTrunc from a 5 pixel height bitmap. I fixed it with

if FResizeTransform.Width < 2 then
FResizeTransform.Width := 2;

if FResizeTransform.Height < 2 then
FResizeTransform.Height := 2;
