I recently upgraded to 10.5.1 (from 10.3.1) and I am suddenly getting script errors when trying to run certain standard tools in the toolbox (e.g., Data Management - Calculate Field) in ArcMap or Catalog. It says there is an invalid pointer and provides a URL: file:///C:/Users/Amanda/AppData/Roaming/ESRI/Desktop10.5/ArcToolbox/Dlg/MdDlgContent.htm. I also am frequently getting the following Windows Security Warning when I try to open/use some tools: An ActiveX control on this page might be unsafe to interact with other parts of the page. Do you want to allow this interaction? It sometimes renders the tool unusable. Help!
