Dear All,

I have an xlsm spreadsheet and one of the worksheets has 12 lots of 9
colums (one for each month of the year). Each of the 9 columns are
grouped, so there are two outline buttons 1 and 2 (2 being the one to
show all columns). When I press 1 everything is okay but when I press
2 (show all columns) excel crashes every time.

The worksheet is protected but has enable outlining set to true.

Any ideas?

Thank you in advance.

Rgds

James
