<p>Hi Walter,</p>
<p>You might also want to take a quick look at what Physics is doing, might not be pretty, but I remember needing to catch more than one event/test to make sure the simulation was suspended correctly across a range of past build releases, perhaps also a case where switching to a desktop view vs. another activity needed to watch for a different event.</p>
<p>Regards,<br>

I see that Clock is using notify::active and then checking<br>
self.props.active. In Turtle Blocks, I had been using<br>
visibility-notify-event. Is the former recommended? More reliable?<br>
<br>
