Access Violation / possible race condition

Access Violation / possible race condition

[GoogleCodeExporter]

One thing that I can test pretty consistently is that it takes some time for 
the Browser field to become valid:

  while Chromium1.Browser = nil do begin
    Sleep(100);
    Application.ProcessMessages;
  end;

Besides that, there must be another internal race, because the MainForm field 
sometimes never becomes valid:

  while Chromium1.Browser.MainFrame = nil do begin
    Sleep(100);
    Application.ProcessMessages;
  end;
  //sometimes we never get here, but get stuck in the loop above
  Chromium1.Browser.MainFrame.LoadUrl('file:///./test.html');

It appears to me that the slower it is to launch the program and load its 
libraries, the more likely the problem is to exhibit itself.

The browser is multithreaded, you have to wait the onaftercreated event to have 
a valid browser instance.
The first time use the DefaultUrl property.

Thanks :-) Works now.  If you create an initial wiki page, I would be happy to 
add some documentation about this.
