ComboBox..._Change() Miss Launches often

[GO GaryFingers]

I have a worksheet, with About 5 to 6 Combo boxes, made with the active x control tool box

They're set up on change, but a couple of them launch themselves without me using them. And can't even close the program properly. The first three worked great!?#%
What makes them operate Automatically like that?

OF course,they are named differently, but all are on Sheet 4 code

The following is the code for one of the combo's, It runs other macros

Private Sub ComboBoxWkshtDateUm_Change()

        'To post Job Date, Um, qty, misc formulas
   
    ComboBoxWkshtDateUm.DropDown
    
    If ComboBoxWkshtDateUm.Value = "Priceformula" Then
        Application.Run "'GO Estimater-2.xlt'!Priceformula"
    End If

    
    If ComboBoxWkshtDateUm.Value = "Date" Then
        Application.Run "'GO Estimater-2.xlt'!PostJobDate"
    End If


    If ComboBoxWkshtDateUm.Value = "UM" Then
        Application.Run "'GO Estimater-2.xlt'!WKSHT_Umpaste"
    End If
    
    
    If ComboBoxWkshtDateUm.Value = "Qty" Then
        Application.Run "'GO Estimater-2.xlt'!PasteFormulaQty"
    End If


    If ComboBoxWkshtDateUm.Value = "Cancel" Then
        ComboBoxWkshtDateUm.Value = "F/D"
        Exit Sub
    End If

	'make value F/D, so that you can pick the same thing again, and have a 'change'

    ComboBoxWkshtDateUm.Value = "F/D"
    ActiveSheet.Select
    ActiveCell.Activate

End Sub

I also don't have a handle on proper Initializing procedure either
Thanx to all that Can Help
