I am on currently the latest build. My browser is simply a form plus a docked WebControl + WebView, not tabbed, no other magics.

I made a "user-friendly" function to "remember my window's last location and page" by:
1. Set the Form's Location and Size in the Load event of the form
2. After 1, call WebView.LoadUrl(LastURL);

However, my users noticed that there is about 5% chance that this action will cause the whole Windows to hang, you can move the cursor but cannot click and type anything(even outside my application).

The solution is to lock (Windows + L) and re-signin.

The hang also happens randomly when moving the Windows(I have "Show window contents while dragging" enabled) while loading a new page.

Can this be avoid?

We do not know the root cause of this issue yet. We are still investigating. We will post again if we find anything. Sorry about it!

Is it possible to solve this issue by creating a WebView through ThreadRunner.CreateWebView and setting the WebControl.WebView to that WebView object?

No. We believe this is due to some internal messaging hook issue. We are working on a new version that hopefully can remove these hooks and once that is done we will test this issue again.
