The TIEColorPalette.OnCellClick event-handler is not triggered by RIGHT-MOUSE-CLICK, although Button: TMouseButton is in the method parameters!!
procedure Tform2.IEColorPalette1CellClick(Button: TMouseButton;
Shift: TShiftState; Index: Integer; aColor: TColor; var Allow: Boolean);
Please fix this bug ASAP. Thank you!
