I have no idea what suddenly went wrong but after a few months worth of developing, this morning Capture Log just started...not Capturing. I can still connect to the PC using the normal Remote... dialogue box, it doesn't throw any errors, but when ti connects ti runs the Capture log for just a few moments and then stops capturing. If I re-enable it, the time scrolls forward in the Perf monitor, but nothing is shown in the log, advanced profiler, or performance monitor.
