The constellation plotter is a next/3.7 thing only. It must have slipped past when creating those examples. That was a real headache, actually, trying to get scripts for both versions that made sense. I rely so much these days on the features of qtgui that are in next. You should be able to change that to a normal qtgui.sink_c(...) and it should work fine. Please let me know if it does and if there are any other files that fail like this. Though, honestly, in the end, that file is about the most uninteresting one in the group. Tom
