Dashboard won't save, nor allow me to do a "save as"

Dashboard won't save, nor allow me to do a "save as"

For some reason, one of my dashboards won't let me make any modifications to it and save?  I get the "do you want to save before closing?' and I say yes and the dialogue box just stays there.  I try to do a "save as" right after I open that dashboard and I get the dialogue box that seems to let me name the new dashboard, but it won't let me save.  The dialogue box just stays there unless I hit cancel or no.

Can you please help?
