I just discovered something weird. I hope I can explain it clearly.
I have a Worksheet_Change event that, among other things, incrememts the
last check number in column J:
Range("I3").End(xlDown)(1, 2) = Application.Max(Range("J:J")) + 1

Occasionally I have reason to manually type in a check number in that
column. If I do, the next time I trigger the Worksheet_Change event, the
check number is NOT incremeted.

Can anyone explain this, and hopefully point me to a fix?
