Thanks Tom. I guess I did not make myself clear. I do have several QT GUI blocks in the program, which I indeed generate using GRC. I have many sliders, a checkbox, and a sink (FFT). If I add a slider, I see it on the screen when I run the new program. When when I add a sink block, there is still only one FFT display, showing the results from one of the FFT blocks. The problem is only with the QT Sink block, not with all the QT blocks.
