Hi all. I've a problem with data entered by scanner. all data entered are matched against the row above. If its different then the cell is highlighted, beep is activated and msg box shown. But when I have large amount of data macro is a bit slow and scanner is collecting data faster then macro can take so when msg box is shown data are still incoming closing msg box it self loosing one enter. Is there any command I can stop getting data from scanner when MSG box is displayed?
