Saving xls file with graphs uses 100% CPU


when trying to convert xls file in 97-2003 format which contains graphs the conversion takes 100% and all memory
see attached project with sample file.

- is there a way to get progress information from save process?
- if the save operation takes extremely long I tried to kill the thread manually but that does not seem to have any effect. Is there a way to do it without killing the whole process?



Thanks for your posting and using Aspose.Cells.

We have looked into this issue and found that the last chart at index 5 of the first worksheet causes some problem and because of that the workbook is unable to convert to pdf. We will look into it further and update you asap.
