I get an ODBC error after running a few scipts. When I reboot, a few scripts will run and then the ODBC error and all scripts fail after that.
I don't have an issue with the same scripts running on QTP 11.
Could you please share what exactly the error is?
Do you observe it at specific line in your script? Which one?
What is your environment?
It is also possible the problem is not related to UFT.
