"Save Project as" -- Beach Ball spinning for a long time????

Hi,

I wanted to make some changes to an Encore project I am working on.

I opened up the Original Project, Deleted the timeline and then replaced it with another encoded timeline.

I then re-linked my chapters and presed File ---- Save Project As ---- renamed it and pressed OK.

I still wanted to keep the original just in case I needed it again.

As soon as I pressed save (for the Save project as), the dialog box came up and on the top of that it says "Save Project as" , but it has been five minutes since I did the "Save as" and I got the Colored Beach Ball spinning in Encore.

Is this supposed to happen. Is it trying to save it?  Or did Encore Freeze?  How long do I wait until I Force quit?

Thanks

Encore 5.1
