4200A Clarius crashing ArgumentNullException .NET Framework

Hello,<br> <br> we are experiencing a randomly occurring crash of Clarius (v.1.10.1) during a conventional IV sweep test, which runs somtimes flawlessly . &quot;An unhandled exception of type 'System.ArgumentNullException' occurred in PresentationFramework.dll; Value cannot be null&quot; is reported, occurring in Clarius.exe.<br> Any hint why this is happening? Potentially is it possible to track/debug the cause?<br> <br> Thanks in advance.

Hello,
We should have asked you for some log files to delve into the underlying reason.

Do you have any extra third-party software installed?  That can sometimes cause issues.

The present version of Clarius on the 4200A is 1.13.
I suggest you download that from tek web site and apply.
Then retest.

If issue persists, please contact your local office for a regional Apps Engineer to assist you.
