Microsoft XP Windows 2000

Have many macros using Range("B2") etc.

Of a sudden none of my macros will run giving me a wrong number of arguments
error. I am having to change put Application. infront of Range("B2")
Application.Range("B2")

Why would this quite taking Range("B2") without application in front?

Have many, many macros with many, many range("xx") lines in it .....

Any explanation?

Thanks in advance ....
