Are there any macros in any open workbook?

Intermittently, a cell erroneously appears outside the range of cells in an
active worksheet. This cell contains duplicate data from one of the other
cells. I am not able to replicate the sequence of events that causes this
cell outside the range of cells to magically appear. I wonder if anyone else
has seen this problem.
Thanks,
