Data Validation use causing parts of other sheet to be visible

[mikeymay]

I am experiencing some activity in a couple of files now where Data Validation is in use.

The files that are experiencing this have the following applied to the visible screen and all other UI screen sin the files

ActiveWindow.Zoom = True

Application.Goto Range("A1"), True

ActiveSheet.Protect Password:=strPassword

Application.DisplayFullScreen = True
Application.DisplayFormulaBar = False
ActiveWindow.DisplayHeadings = False
ActiveWindow.DisplayWorkbookTabs = False

In the file I am currently experiencing the issue I have a sheet named 'Launch Page' and a 'Product Selection' Page.

When using the data validation cell in 'Product Selection' page, some of the 'Launch Page' cells bleed into the 'Selection Page'

Below is an image of the Launch Page

This is an image of the Product sheet prior to any interaction with the sheet

And below is an image of the Product page as soon as I start to interact with the sheet

Previously I have used

Private Sub Worksheet_Change(ByVal Target As Range)

Application.ScreenUpdating = False

Application.ScreenUpdating = True

End Sub

which deals with the problem, but ideally I don't want to have the problem.

TIA
