Sending WM_COPY message to IE.

Hello everybody,

In short:
Sending WM_COPY message from my app to Word, Excel or Notepad works. But
sending it to Internet Explorer, Firefox or Outlook Express does not work:
the clipboard remains unchanged.

In long:
I'm writting the following application:
 - no visible user interface
 - when the user is over any text on any other app (Word, Access, Internet
Explorer, Outlook...), he selects a telephone number, he presses F9, and the
computer will make the call to that number for him.
(Image you are browsing a hotel's site, you want to contact it, on the web
page you see the phone to call, so you just select it and press F9! I find
it nice)

 ? There's no problem from the telephony point of view (CTI).
 ? I'm also able to "listen" that the user has pressed F9, no matter which
application had the focus (I hook the WM_CHAR message of any window using
the idea found here: http://www.codeproject.com/system/KeyLogger.asp)
 ? And I can also send a WM_COPY message to that window where F9 has been
pressed, so that I load the selected text up to the clipboard. (code below)
 ? Then I can retrieve the content of the clipboard (code found here:
http://www.codeproject.com/clipboard/archerclipboard1.asp) and, if it is a
phone number, I order the makeCall.

My problem is, as I said:
This works fine with MS Word, Excel, Notepad... BUT sending WM_COPY message
to Internet Explorer, Firefox & Outlook Express does not work: the clipboard
remains unchanged.
I also tried to send this message recursively not only to the actual focused
window, but also to all of its parents. But it still does not work.
I also tried to PostMessage, instead of SendMessage, but this didn't work
either.

Are these applications somehow "protected" against sending messages to their
message-queues?
Any ideas on how could I solve my problem or a better approach?

Thank you!
