Like in my previous post, I found this strange behaviour when testing some sample files for my next article about PowerPivot in a computer magazine. In some cases, Excel 2010 does not correctly display the selected cell, especially if you are freezing rows. This behaviour does not appear in Excel 2007.
To reproduce the error, you may first create a new workbook in Excel 2010 and store the file. It does not matter whether you choose the old file format XLS or the new modern XLSX format. I created the two sheets „Fixed“ and „Standard“ in my workbook and formatted some cells as you can see in the screenshots below. Please note, that only Excel 2010 in German is currently available for me, but I think, this will be suffisent for the demonstration.
The areas I to IV are containing merged cells. And the pane was freezed between row 7 and 8. If you select cell D2 by clicking with the mouse on this cell, then select the worksheet „Standard“ and go back to the sheet „Fixed“, the selected cell is correctly displayed.
An interesting effect occurs if you click on other cells. The follwing series of screenshots shows this behaviour of Excel 2010. First, I selected area I, as you can see below:
