Sorry I didn't mention it,

of course I post a message to the control to clear and refresh it, sure it

would throw an exception trying to free a control while executing its method.

The exception is thrown only when the RichView is active

I run a simple test: post a message to RichView to refresh, but called Clear

after a 5 sec delay. An exception was thrown after 5 sec. If I pressed any

button on the form (doing nothing, just to remove focus from the RichView

document), everything worked fine.

Anyway, I'm happy with my workaround, so nevermind.
