Excel 2003, when I click on a particular cell it gets deselected

[towinwin]

While using Excel 2003, when I click on a particular cell, within 30 seconds,
that particular cell gets deselected followed by the workbook. So each time I
need to click either the cell or workbook to enter data in that particular
sheet.

There could be event code that is being fired. Does this happen if you open the workbook with
macros disabled?
