Hello,
I changed defaut cursor for the plottable (formsPlot1.Cursor) to another (Cross), It works, when the mouse enter to the plottable, it become a cross and when the cursor exit it go back to defaut cursor (Arrow).
But if the cursor go on a draggable label, it become a "Hand", and when the cursor exit the draggable text the cursor go back to defaut (Arrow) not cross.
Thank you
