Description
An application using the TWebBrowser component crashes with an unhandled exception when navigating to a web page containing a Silverlight application. It crashes on Windows XP, but works fine onn Windows Vista.

If you create a WinForms application in .Net (3.5 was used for testing this) doing the same, it works on both XP and Vista.
Steps to Reproduce:
Use the demo project in the Coolstuff directory and navigate to a silverlight containing web page.
Workarounds
No known workarround when you need to support XP.

> a web page containing a Silverlight application.
Could you please provide the URL to reproduce your issue?

same problem, although I have D2006. some more test links:

http://demo.mapdotnet.com/MDNUXHurricaneDemo/http://www.retouchgenie.com/Default.aspx?RID=RG3423fPhttp://demos.telerik.com/silverlight/default.aspx#Chart/FirstLookhttp://www.wintellect.com/silverlight/pageturndemo/http://mosaicmaniac.com/?c=Zoom&i=horse5

try clicking some links on these pages.
The app will crash after the silverlight loading screen reaches 99%.
This is definitely a problem on the delphi side because I created a windowsapp in VS.NET 2008 studio with a browser and there I can navigate the pages without any problem...

In fact, it crashes when navigating to any web page containing a Silverlight control. It seems to crash as the Silverlight application initiates. Try, for example:

http://www.trt.net.tr/Canli/AnaSayfa.aspx?Kanal=TV1

(This is a showcase pointer to from www.silverlight.net)

The same problem can be found inside Delphi 2009 IDE itself, if you go to the welcome page, and navigate to a web page containing Silverlight, the whole IDE crashes with an unhandled exception.

After more testing, in the case of the Delphi IDE the crash does not happen consequently.

I have noted that certain Silverlight pages do work correctly, but if you try to load that same page 5 minutes later it will crash. Really strange..

I am experiencing this problem as well using windows XP and D7. Is delphi9 not supposed to have full support for Silverlight?

Kenneth Clubb at 6/1/2009 8:28:24 AM -
I am also have this problem.  Please identify if this problem is being fixed.

It is trivial to reproduce. On XP, create a new VCL Forms app and drop a TWeBrowser on it.

Add a button, and a click handler, then in the click handler, add a call to: Navigate("http://silverlight.net")  
Crashes every time.
