Hey Clowe,

Thanks for writing in.

We've recently received a few reports on this, and have uncovered a bug in the latest PingPlotter release that seems to be causing this issue. Our development team is aware of this, and looking into a potential fix for our next point release (which we're hoping to have out soon!).

Sorry for any inconvenience this may have caused. If you happen to have any questions, or if there's anything else we can help out with - please let us know!

Best wishes,

-Gary
