I have a number of scripts that use Perl's Win32::OLE to manipulate Excel. I recently upgraded my machine, and am now running Excel 2013 (I was running Excel 2010, both the 32 bit versions). Whenever the script opens up Excel (or maybe it is the workbook), a window appears -- this didn't used to happen. The problem is I'm doing a fair amount of drawing, and the drawing is remarkably slower when the window is open, so I want it closed. Any clue on what I need to do to restore the Excel 2010 behavior of not opening a window?
