Excel 2007, on Windows XP.
When the user selects some cells, they can then right-click and 'Copy'. However, when they right click to prepare to Paste (or Paste Special), those two options are greyed out. They can, however, do the keyboard shortcut to Paste or Paste Special.
If I start Excel in Safe Mode, everything works fine. However, I cannot locate the 'thing' that is causing the issue. There is nothing in either of the two XL Start folders, the only add-in listed I disable, with no effect. I have looked everywhere I can think of as to where this 'offending loader' may be, but I cannot find it.
Any suggestions as to where I can look?
