Hello,

Previously I shortened an excel spreadsheet so that only rows 1-199 show,
everything below row 199 is grey.

When I go in now to add a column, the sheet freezes on me and I have to shut
it down.

Is the solution to open up the rows again to the end, for example row 66xxx?
If so, how do I do this?

Or is there a way to add a column without the sheet freezing up?

Tahnk you fo ryour help
