Cumulus Support

Cumulus suddenly bounced an error dialog box at me - nothing else obviously hogging resources / having problems.

Tried to allow to continue running - error shortly re-appeared.
Cumulus closed and restarted.

Hmm. Sometimes I get these where I say "it's not crashed in my code, and I don't know why it's crashed", but usually I can say what was going on and which bit it was that crashed. But I haven't the faintest idea what's going on here! I'll do some digging...
