Other users are freezing without knowing it??
 

Several users on a network Excel file freeze rows in the worksheet. They are
not savy enough to know how to do it intentionally and the places it ends up
frozen is very haphazard. Can I lock the freeze that should be maintained?
And, can freeze be done any other way than the drop-down menu?

Do you mean they freeze panes...

the places it ends up
frozen is very haphazard
or just that the sheet opens to a different range than intended?

Can I lock the freeze that should be maintained?
Not that I'm aware of - but you can use VBA to ensure that the file
displays what you intend when it's selected.

And, can freeze be done any other way than the drop-down menu?
Yes, with programming like VB.

Regardless, you can control what’s displayed when the file is opened:

Private Sub Workbook_Open()
'Make this the sheet you want displayed
Sheet1.Activate

'This tests to see if panes are frozen
'and unfreezes if they are
If ActiveWindow.FreezePanes = True _
Then ActiveWindow.FreezePanes = False

'make this the most upper-left cell
'that you want to be unfrozen
Range("a2").Select

'freeze the panes at your selection
ActiveWindow.FreezePanes = True

End Sub

See this site if you’re not familiar with using VBA:
http://www.contextures.com/xlvba01.html
and go to the part titled: Copy Code to a Workbook Module (the example
above is workbook code)

You’ll have to adjust the ranges in the example to get the results
that you want – this site may help:
