Isn't this standard behavior? No, it's not standard. Try it with Explorer. The selection should only get cleared on a click event. A click doesn't occur until the mouse button has been pressed *and* released without the cursor moving outside a specified area. If the cursor moves too far, then the operation is a drag, not a click. > Just so I understand what you are asking for, how do you think initiating a > drag/drop after multi-selects should work? The selection and the dragging are allowed to be two separate operations. Otherwise, it requires too much planning from the user on the last selection operation. The user would need to know what the last selection will be so that he or she can begin dragging. Otherwise, the user would need to unselect something just so that selecting it can begin a drag operation. -- Rob _______________________________________________ Delphi mailing list -> Delphi@elists.org http://www.elists.org/mailman/listinfo/delphi
