[tde-users] strange visitors on top

Does anybody know what these processes represent? applet.py agent at-spi-bus-laun They show up in top, running as processes under my user name, PIDs are all close together in the 2600 range, but they are new visitors that I've never seen before. I've tried to track them down to their source, so far with no luck. I've had some other issues, too, but I don't know if they are related. Just getting used to running TDE on a different and newer machine, so I expect that things will change and I need to make adjustments. But I can't imagine what I might have installed that does this. These processes all run at near 100% CPU, although I don't really have much else running at present. In any case, since I haven't seen them ever before yesterday, I want to know. Any help or suggestions are appreciated. Bill
