Hello:

I had very unusual experience with Excel this morning. I had set up a workbook last week to do some calculations, and I opened it up this morning to continue my work. I wanted to copy a formula from one cell to others in the same column. I used the same procedure I had used a million times before - selected the object cell, hit crtl-C to copy, then selected the target cell(s), and finally, hit ctrl-V to copy the formulas. Well it seemed to copy them correctly, the cell references all changed appropriately for the copied cells, but the results were not correct. The result for all the cells was the result for the original cell, just copied over and over again, even though the formulas appeared to address different cells with different values. A little additional info: 1) When setting up the workbook, I had tried to insert multiple worksheets at once instead of just inserting one at a time, as I had always done previously, and 2) When opening the workbook this morning, in the header above the toolbar, where the workbook name appears, there was a notation "[Group]" after the name, which I had never seen before. I shut down Excel and re-opened the workbook, thinking that I had inadvertently hit a strange key combination on opening, but that didn't work. I shut down and rebooted my PC, but that didn't work. Finally, after I opened up a blank sheet as a "New" workbook, entered some data and did the ctrl-C, crtl-V sequence, it seemed to reset everything to work as expected. Weird. Any ideas? Thanks alot.
