I seem to see a difference in behavior in Excel 2013 of an autoexecuting macro (or VBA application) if I open the Excel file by clicking on it vs if I open Excel first and then open the Excel file containing this macro. Specifically I have a small animation that does not seem to execute in real time if I open by clicking on the file, but if I open Excel first and then open this file, it works the way it is supposed to. The same code works fine in Excel 2007 and Excel 2010. Any suggestions on why this happens and any workarounds?
