Quartus II Settings File changed outside of Quartus II warning?

Hi,

I see this warning pop up when I compile my design: "The Quartus II Settings File changed outside of the Quartus II software and contains errors. Rewriting the Quartus II Settings File with the current state of assignments in the Quartus II software".

I do modify the .qsf file outside of Quartus. I am trying to figure out which line in caused the warning above, is there any way to do so? The pop up box shows up after A&S, P&R, program file, and timing analysis, and I have to click OK every time to make the compiling continues. Once the project compile, everything do seems to work.


Thanks
