When automating the use of a Saleae device using a script (e.g. a python program) and your API, a pop up window that that prevent the application from responding to scripts via its API is disastrous: the application does not respond, but is not dead.
In practice, this happens after a crash when the application pops-up a window to ask whether to send a bug report.
Adding insult to injury, if you manage to kill the application (listed by the OS as "Main" for some reason) and restart it, it starts with the same pop up. So this workaround is blocked.
BTW: it's the pop up window that's the problem. Either sending or not sending bug reports is fine.
