After following your testing I would recommend two things:
- Check to see if there is an updated version of ActiveX available that may resolve your issue. I would check for that on the Microsoft sites as well as SAP.
- Put up a post on the SAP Crystal forum asking for a solution. I have already checked their forum this morning but was not able to find anything related.
For now I guess you'll just have to view your app in compatibility mode or go back to IE10 until there is a fix.
EDIT: A solution was found over at the SAP forums. It was suggested to update his CR Basic version to the CR for VS version. Please see the thread here.
