text disapearing in a text box
 

I put a text box on a chart. After typing it in (it was a long text) I saved
the chart I could still see all the text. After I saved it, I created a PDF.
It was still fine. After I closed excel. The next time I opened the chart
part of the text was gone. I tried to resize the text box, but part of the
text was still gone. When I oringinally save the chart I didn't get an error
message about the size and the pdf after the save showed all of the text.
Thanks
