Excel Hidden columns

[Shane Browning]

I have just opened an Excel s/sheet that I used last week and find that in
two of the tabs i now have hidden colums (A to Z). I have done nothing to
hide them and everything I do to try and unhide them does not work.?
Please help

It might be that you've set Freeze Panes. Try Window, Unfreeze Panes.
