Unhide hidden columns

Solved
Hello,
Don't ask me how I did it, but I managed to hide all the columns from A-F, and now my sheet starts with column G...
The problem is I can't unhide the hidden ones anymore...

Configuration: Windows 8 / Chrome 29.0.1547.62

  1. Try to select the entire sheet by clicking in the top left corner, then set the column width to 10 or 12 (FORMAT command).
