Many thanks for that. I think it might have happened when the CurrentCost meter
output some history data, which my code tried to parse as live data and fell 
over.

I've tried to fix the bug:
http://currentcostgui.googlecode.com/files/currentcost-source-0.9.28b.zip 
http://currentcostgui.googlecode.com/files/currentcost-0.9.28b.zip (still 
uploading,
but will be there in a few mins)

Kind regards, D

Sorry for not getting back to you but have been busy with other things.

Seems you have changed the problem....don't get an error message from 
currentcost 
anymore ...get a WINDOWS error for currentcost.exe now! 

AppName: currentcost.exe     AppVer: 0.0.0.0     ModName: 
matplotlib._path.pyd
ModVer: 0.0.0.0  Offset: 0000ce75

I have included a diagnotic file as well (have been saving a few of these from 
other 
similar crashes if more examples will help...let me know!)

thanks

steve
