An Error while saving a stand alone application

[Joe Lewis Wilkins]

Hi all,

I guess it was inevitable, but a stack that I have saved to a stand  
alone several times, successfully, now presents me with an Error  
while saving dialog and abotss the process.

How can I determine what I have introduced into the stack that would  
cause this. I have made some fairly major changes, but not real  
complications. I added and deleted a couple of cards, but nothing  
earth shattering.

Thoughts as to how to proceed would be appreciated. I don't like the  
prospect of starting over again.

TIA,

Joe Wilkins
