Does SignalTap work with other ICs in the JTAG chain?

Does Quartus II SignalTap work with ICs in the JTAG chain other than the Altera FPGA where SignalTap is being utilized? I get "Invalid JTAG configuration" in the SignalTap II Logic Analyzer stp wind...

It should work fine. In the Quartus Programmer (you can't set up the chain from the .stp file), you may need to add the other device in the JTAG chain as a non-FPGA device so that the Programmer ignores it.
