I have tried the 'detach profilee' option and disable profiling, but neither seem to work. I started profiling an application (attach to existing process), then wanted to compare results with another profiler (Ants) but it could not attach because JT was still attached (even after exiting JT). Starting JT again, when it loaded the list of processes it showed that the process I previously p attached to was still sampling, so it seems like the detaching didn't work.
