Attached Visual Studio Debugger after starting PulseView earlier

PulseView can go for days or hours without crashing (when just left running, but not acquiring). But then when pressing the space bar or clicking Run to perform an acquisition, it will hang sometimes.

I don't know if this is fact, but it seems more likely to hang if the sampling rate has been changed from what is first chosen before doing the first acquisition - but that may be superstition. 

I attached Visual Studio to PulseView after starting it and just left it running in the background while doing ad hoc acquisitions, and when PulseView crashed, I got this screenshot of Visual Studio - I don't know if it will help to determine where the crash/hang occurs.
