Cumulus Support

This is the 2nd time I've had this error - I try to zoom in on the wind graph and immediately the error comes up. Usually zooming in is fine though.
Attached bug report - it contains the reports of both the errors I had
Might be another bug in the chart component?

Well, it's certainly crashing in the chart component. In both case, the FTP component had just suspended waiting for a response, which allowed the chart component to get in and start doing things.

By coincidence, I've moved realtime ftp into its own thread in build 955, so that may have a nice side effect of stopping this problem occurring.
