When a report is displayed on the screen (eg Debtors Report) if you click the report and use the up/down arrows on the keyboard to scroll through each line item, the report skips a line when the screen also scrolls.
eg…if you are on line 54 of the report pressing the up arrow, it will stop on 53,52,51,50, but when the screen has to scroll in the other direction, it skips to 48 and misses line 49. Not a big deal, but annoying when you are counting through the list eg to see how many customers owe over £1K
