I have a user that owns a Dimension with a 19" M990 color monitor. He says that when he drags an icon, it leaves a copy of the icon as it is drug along the screen. Almost like it isn't refreshing or refresh rate is wrong. He says it isn't and the connection is tight. Everything I have suggested has not worked. Should I have him remove the monitor in Device manager and let Windows 98 detect it ? Any suggestions would help. Also...how do you reset these monitors back to factory defaults ?

Thank you
