Hi,

I created a WPF UI designed to be loaded in a different process, for CLR incompatibility reason to application. This application (from 3rd party) will host my UI. Everything works fine until I clicked my UI, the whole application hangs. I'm able to find the root cause, and it's a group box ATL user control. The group box acts as a panel to my UI. If I try to hide the group box, using some win32 API's, the issue will not happen.

I have several options on fixing this issue, one of them is to inform the 3rd party company and ask them to fix. But I cannot enforce this to them, so I would like to know if I can do some work around on my end to prevent this from happening.

Can anyone give me explanation why this happen?

Thank you very much.
