Can't change "Set as Start Page"

I'm using Visual Studio 2012 and I'm trying to change the start page from Default.aspx to PrintMoldingKanban.aspx.

I have done this before and all of a sudden it is not working.  I right click PrintMoldingKanban.aspx. and then click "Set as Start Page".

When I go into Properties for the project, the  Start action section of the Web tab shows that the Specific Page radio button is click and PrintMoldingKanban.aspx. is in the text box.

When I run it in debug it appears correctly. but when I publish the project to my PC and enter //localhost/PrintMoldingKanban, I get the default.aspx page.

Any suggestions???
