    what version are you using and what are you doing to run into the bug?

    what happens if you double click the <none> in the File Column and FPGA row?

    The QuartusII version is 9.1 SP2.

    I am going to program the JTAG chain by adding config file to device and then the bug happen.

    when i double click the <none> one window popup to select the config file, but the bug take place when i select the pof or jed and click ok.

    Hope your further help, this problem has blocked me some days. Thank you!

    you might try installing 11.1sp1 full or stand alone programmer

    i'm guessing you are trying to program the CPLD with the .pof?
