Hi mgroeger,

Is this still reproducible without using threads? Please note that our controls and components are not thread safe, so you would have to handle such scenarios yourself.

How can I reproduce this without using threads?

Thank you for your research and details! Could you please clarify what do you mean by suspend? What do I need to do?

Your computer needs to go into sleep mode (energy saving). On a notebook you normally and easilly can do this by tapping on the power button of the notebook.

You should not do this with the Start-Button, because that way the form looses focuis.

Hello,

I created the following case for you: 'CAS-115885-D7Z2M5' and will update you through it.

Do you have an update for this issue? I'm getting same error with the latest version of Infragistics.

Hi Pramod,

You can view the status of all development issues connected to this case from the "Development Issues" tab, when viewing this case on the "My Support Requests" page of our website.

I think the fix is in 13.1 and later versions.

Hello,

I have the same problem.
When the notebook is on hold or suspended sometimes get the following error (see attached image toolbars):

Note: This error does not always happen. It is random.
