Hello,

Just offering this from the 1.1.0.15 build, noting that it's the current BETA. Since upgrading from 1.1.0.4, I started getting these .NET Framework unhandled exception warnings. It seems to do with the graphs. I don't have any additional details to give other than BC runs in the background, tracking what it does, and this just crops up on its own. if I don't have any devices activated for tracking, no warning like this, but when I have devices enabled and let them run for a while (with the graphs showing the data), I get this.

On a separate matter with the graphs, I note they like to clear out and reset any time their settings are changed. I guess I'd need to go back to 1.1.0.4 to see if the same things happen, but I feel that in 1.1.0.4, I could change the time span and still have the data appear, just at a different scale. Also, if I open the graph settings and click OK without changing anything, the graph completely clears.

Hopefully, this is helpful as the BETA develops!
