nsIWebBrowserChrome methods not being called (in 1.3b)

[Martin Kenny]

Hi,

I recently decided to put together a test embedding application (Win32, 
ATL) from scratch, using the "Gecko Embedding Basics" document as a guide.

I had something working in an hour or two, but what's been bugging me 
ever since is that I can't get any of the nsIWebBrowserChrome methods 
(notably SetStatus) to be called at all. This results in no status text 
when hovering the mouse over a link. When I implement BrowserChromeImpl, 
OnStateChange *is* called as the page loading state changes.

Nothing seems to even QueryInterface for nsIWebBrowserChrome.

The code to create the browser instance is shown below.

I've kept implementing other interfaces and calling extra methods (as 
seen in MfcEmbed) in the hope that something would make it start calling 
the SetStatus method, but no go.

If anyone has seen anything like this, or has a possible explanation, it 
would be really appreciated.

Marty.
