Is there a way to prevent the "Code execution has been interrupted" error?
I'm thinking there is not, but perhaps my code is incomplete or inadequate.

A worksheet has the following event handler: (A similar handler exists for
the workbook.)

Private Sub Worksheet_Deactivate()
'Redisplay Formula Bar when changing to another worksheet
On Error Resume Next
Application.DisplayFormulaBar = True
End Sub

When I start to Alt-Tab to change to another window and use the Esc key to
change my mind then the Esc key must be pressed a second time to avoid the
interruption error when any code is executed. Of course, code will be
executed if I change worksheets, workbooks, click a button, etc.

Any suggestions?
