Hi,

I have worked with many versions of Excel, this is the first time I've experienced this issue - but it's happened twice now; I certainly want to stop it before the 3rd time!

I'm newly using Excel 2010,. This spreadsheet is a work-in-progress, originally started in Excel 2007. I routinely hide and unhide columns depending on what I need to see, printing requirements, etc. It's likely that I had hidden some columns then saved the spreadsheet but I've done that many time without issue in the past. For the second time now though 4 of the columns are now completely gone. The lettering is correct (so no indication that they are still hidden), there is no info there. I was just doing a basic database, sums, etc but nothing fancy, no macros, nothing. It did include addresses that I mailmerged with Word, a few notes and dates, and other info columns.

Any idea how this happened? I'm presuming the data is long gone.... I did check the "Inspect Document" results - nothing.

An old post that is similar: http://www.excelforum.com/excel-gene...s-missing.html

Thanks for any help/insight!
