Multiple Windows
 

When I open OF lately, two windows open, even though I only had one open when I last closed it. Both windows are titled the same perspective name. One window is in Planning view; one in Context view. Neither is the way I left the perspective window when I closed the last time. Does anybody know why this is happening and how I can make it stop?

I have tried closing the other window, fixing the perspective window the way I want it, and re-saving the perspective. I have also tried deleting the perspective and creating it anew, but I still get two not quite right windows.
