Titles not able to be changed on charts

Just this morning all the titles on my charts that I created via a "Save As" from another chart had their title (within the chart not on the sidebar) default to the name of the chart that they had been saved from. When I go to edit the name of the title it does not change. There is no error message or anything it just doesn't save the change when I hit save. When I reopen the the title is still the same title. I would appreciate your help remedying the problem. It was not a problem until this morning so it may have been something you changed.

Also I am having a problem with my ability to change the colors on line charts. The button to change the color is unresponsive as in my previous forum post.

My database is still shared.

Thanks,

Lexie
