Hyperlink doesn't respond to clicks?

Using the Feb. CTP:

A component of my application converts HTML coming in from a socket to XAML
using a series of regular expressions, and calls the XamlReader.Load(string)
method to turn the XAML into a Paragraph object, which is then inserted into
a RichTextBox.

HTML hyperlinks, <a href="http://url.com">MyUrl</a>, get translated into the
XAML expression <Hyperlink NavigateUri="http://url.com">MyUrl</Hyperlink>. A
full Paragraph might look like: <Paragraph xmlns="..."
xml:space="preserve">Go to this keen site: <Hyperlink NavigateUri="...">My
Site</Hyperlink>!</Paragraph>

The RTB displays everything very nicely, but the hyperlink doesn't behave
"normally." The text color is not the default hyperlink color, although it
is a different color from the rest of the RTB text and is underlined. The
cursor does not change to a "hyperlink" cursor when the user mouses over it.
But most importantly, the hyperlink doesn't respond to clicks at all.
Attempting to circumnavigate this by adding a Click="hyperlink_click" event
handler in the XAML results in the parser throwing an exception, saying that
the XAML must be compiled (and not parsed, I guess?)

Any advice for getting operable hyperlinks?

Yeah, there's compiled xaml, then there's XamlReader.Load, and the latter
doesn't support events because there's no obvious code to hook them up to.

That doesn't explain why hyperlinks can't be clicked, though, can you send
us a repro file? Thanks.

Not a problem - what's the best way to send what you need? It's a bit lengthy
to repost a reproduction in its entirety on the newsgroup.

As a workaround, I came up with the idea of iterating through the
Paragraph's Inline objects looking for hyperlinks and manually attaching a
MouseDown event (Click still doesn't work). This works for the most part,
but iterating through all the top-level inlines doesn't touch every hyperlink
that have been buried in formatting. What's a good way to visit every Inline
in a Block?

Are there any NavigationWindow or Frame elements in the parent chain of the
Hyperlink?
Hyperlink initiates navigation by bubbling a navigation routed event through
its parent chain.
If an element in the parent chain (usually NavigationWindow or Frame)
handles the event then navigation happens otherwise noop.

Probably best to file on ladybug,

In terms of enumerating all hyperlinks, I believe you can do this using
LogicalTreeHelper.
