Hello Wooltown,

Can you please give us more information about your application under test?
Is it possible to post a Ranorex Snapshot file?
Additionally it would be great to get access to your application if this is possible in order to analyze the problem.
Does the issue also occur when you are using other browsers?

Regards,
Bernhard

Had the same issue in one of my test runs today. Sent email to support.

I'm also experiencing this issue extensively. Please let me know how I can help demonstrate it?

Hi brendaj,

Please provide some additional information about your issue.
May I also ask you to answer the following questions?

• Which version of Ranorex is installed on your machine?
• Is it possible to post a Ranorex Snapshot file?
• Which Browser are you using?
• Is this post about the same exception?

If you don’t want to post the information about your issue here in the public forum, you can send an email to [email protected]

Thank you in advance.

Hi,
Did anyone find out the reason for this error message? I have Ranorex 5.1.1 & Windows 7.
I have been using Ranorex (older version) for last two years and never got this error.
But in last couple days I have been noticing it.
Although this error did not cause my automation to fail and all the tests ran fine. But I want to nail down the reason for this.
Thanks,
Fatima

Hi Fatima,

Can you please give us more information about your test and your application? If your test has no issues during the run it could also come from another application.
Can you please check which element is the reason for this message? It would be great to get a Ranorex Snapshot file or access to your application.

Regards,
Bernhard
