It seems that you are using RadPivotGrid
from the Telerik UI for WinForms suite in OpenEdge environment. By design, RadPivotGrid
's engine internally uses multi threading which can't be stopped. As far as I know, multi threading is not supported in OpenEdge: https://stackoverflow.com/questions/46153177/multithreading-in-openedge/46153343
Please note that for OpenEdge related topics the preferred places to submit a technical question are Salesforce and the Progress Community: https://community.progress.com/
You can log in to these websites straight from your Progress account: https://progresslink.progress.com/supportlink
Thus, the appropriate support engineers would gladly assist you.
I hope this information helps. If you need any further assistance regarding the Telerik UI for WinForms suite please don't hesitate to contact me.
