when the user moves the mouse over the get controls involved the lines are displayed or if the user selects a record in the xbrowse the pixel or the colored circle at the x,y positions is displayed
When instead the user moves the mouse over the folders or in the dialog I call the MyOverDlg(.f.) function to end the display of the graphics

The problem is that the pixel remains in memory as you can see from this image.

I discovered that the EXE is still in the computer's memory.

How can I solve it?
