2 lines taking 7sec

What would be causing these, seemingly innocuous lines of code to take, consistantly, 7-8sec after an NSB.MsgBox tap?

Function HomeLogoutButtonResponse(choice)
  If choice = "Cancel" Then Exit Function
  HomeForm.hide()
  OpeningForm.show()
End Function

Do you have any onhide() or onshow() functions?

No. Got an onresize but that is not being triggered.
