I've created a userform to gather question responses and save them to a
spreadsheet. I made a "Save" button which saves the spreadsheet and then
asks if the user wants to quit. The user form is unloaded and the
application quits.

For some reason, when the user returns to the form, to continue entering in
data, Excel locks up after 1 or 2 items entered.

here is the workbook open code:
Sub Workbook_Open()
removerandc
QWiz.MultiPage1.Value = 0
QWiz.settips
QWiz.UpdateProgress
QWiz.Show
Unload QWiz
restorerandc
Application.Quit
End Sub

and here is the save button code:
Private Sub Savebtn_Click()
UpdateProgress
ActiveWorkbook.Save
exitsurvey = MsgBox("UAS Evaluation progress saved. Exit Survey?", vbYesNo,
"Exit Survey?")
If exitsurvey = 6 Then
Application.DisplayAlerts = False
Unload QWiz
End If
End Sub
--

I am truly stumped. Any ideas would be great.

Thanks,
Gene
