I have found what I believe to be a bug. I have researched it
extensively but have found nothing. I apologize if I missed something.
This is what I have got.
Excel 2010 in Windows 7.
1. Open New workbook
2. Select entire sheet, right click and clear checks from Format
3. Select any column, check "locked" on Protection tab. (use "L" for
4. Select and HIDE columns M, N and O.
5. Protect sheet.
6. Select column L thru P (in order to unhide)
7. Right click
At this point, Excel locks up and requires closure of the program to
regain control. This happens on every pc that I have tried it on. It
appears to be right clicking on a locked column in a protected worksheet
is the issue.
Anyone seen this before? Any info would be helpful.
