Just had an error this morning, no hang or anything just an Access Violation. Clicked cancel to end program and restarted OK.
Just a thought Stuart,
Are you also running any derivatives of my harvesting/graphing scripts at the same time as rs-ux/rs-w?
I found that one or the other can freeze, presumably when both attempt to access the modem/router at the same time.
Even staggering the timing of the data harvesting doesn't quite resolve the issue as it appears that eventually they catch up with each other.
My comments may be a red herring though.
As mentioned by Eric, it is quite rare & the devil to diagnose, thus cannot yet be definitely attributed to a timing clash.
Do you maybe have any other software running that may just attempt to access the modem/router at the same time?
