Although I don't think means anything or is a concern. However, most times with Access most every behavior have a reason (one would say likewise in life). I've noticed that when I open some of my SubForms (in Datasheet view) within the master form the first field (data) is blinking. Usually when I expand & collapse the SubForm the blinking will stop,but will blink if I close/open the SubForm again the first field (data) in blinking. Sorry if "I'm being silly; just take precautious.
Any advise/suggestions will be greatly appreciated! Thanks in advanced.
