I have put a workbook open procedure in my model on the 'This Workbook' sheet.

Public Sub WorkBook_Open()

AnalysisToolPak_Exists 'Procedure to ensure Analysis toolpak is operational
'Maximize worksheet to calculate dimensions
Application.WindowState = xlMaximized
Application.ScreenUpdating = False
TaskBar_Hide 'Procedure to hide taskbar
Application.DisplayFullScreen = True
With Application
.Calculation = xlAutomatic
.Iteration = True
.MaxIterations = 50
.MaxChange = 0.001
End With
Application.ScreenUpdating = True
ActiveWorkbook.PrecisionAsDisplayed = False
Health_warningfrm.Show 'Calls "Splash" screen to warn users of model limitations

Load Mainscreen
Mainscreen.Show

End Sub

My problem is that it will not run when the workbook is opening. It can be run from within Excel via Tools Macro Run. It did run at an earlier stage in the devlopment process of the model. Latterly it ran occasionally, but now it seems it never works.

I am running Excel 2002, though it was originally developed in Excel 2000.

Anyone any ideas as to what maybe wrong.

Hi
some ideas:
- check that you really have put this code in your
workbook module
- check if application events are enabled. e.g. enter the
following line in the immediate Window:
applicationenableevents=true
and try again
