Thanks Logit.
This code is for an excel spreadsheet.
I was looking for code which is compatible with ms word?
Thanks

Much of the code is the same for Word and Excel but, since you haven't provided any details about what kind of textbox you're referring to (people call all sorts of things in Word textboxes) or how it is to be identified, it's impossible to code a solution for your specific situation. Obviously, too, whatever the textbox is, it's liable to require different code from that used for a caption. You also haven't told us anything about when this flashing is supposed to occur.
