TrackObject procedure

Hey, is vs.TrackObject work in Pyton VW 2016? I need red highlight selection for my tool. I can run this and red selection works good. How can I do something after mouse click during TrackObject works? After mouse click tool stop working, but i need tool still active or run again. I need tool similar "Number Instrument" from spotlight. I known that this procedure do not block script execution. So i need write all inside callback function. Is it true ? It is many topics at forum but

This is my simple script only for test. It works, but I can not do anything after mouse click. Script go terminate. I tried put TrackObject inside loop but script hang. I tried use vs.MouseDown() but it gets no values. I tried many things, no result. Any idea? I can resolve my problem using vs.GetPt() instead TrackObject but GetPt do not red highlight objects. Red highlight is more interactive so its better for me. TriedObject works in VectorScript because it stop execute script. In
