Column grouping and hiding being over-ridden when sheet opened

[pignick]

In a large workbook with a number of worksheets, some worksheets have certain
columns hidden or grouped and normally viewed at level 1. Also, some
worksheets have code that runs on sheet activation and/or de-activation, and
if I move from one of those to a worksheet containing the grouping it is
ungrouped, whereas moving to it from other worksheets doesn't cause the
problem and it remains as saved. Any ideas please?

Also, can someone please explain the difference (if there is any) between
Activate/De-Activate and Open/Close when writing code related to Events.

Having had no replies to my initial question, can I explain it in a bit more
detail to see if that helps.

When I move from the worksheet containing the following code to another
worksheet the columns AO are selected in that sheet, and I am trying to
understand why this happens as I thought that "End Sub" stopped the code.

Private Sub WorkSheet_DeActivate()

ActiveSheet.Unprotect
ActiveSheet.Columns("AO").Select
Selection.EntireColumn.Hidden = False
ActiveSheet.Protect

End Sub

I think the same thing must be happening when I move from the sheet
containing that code to another sheet containing some grouped columns that
normally display at level 1, and these get ungrouped (even though the sheet
is protected) presumably because the instruction to unprotect and then unhide
the columns is being given.

No doubt the answer to this is simple and I'm overlooking it, but any help
would be welcome.

try using

application.enableevents = false

at the beginning of your coding and

application.enableevents = true

at the end.

this will stop your events from triggering other events, which is what
i believe you are describing.
hope that helps!

Thank you Susan, but I don't think that has fully resolved the problem. I am
out of the office now for a few days but will take another look and try again.
In the meantime if anyone else has any suggestions please post them.
