TEmbeddedWB & undo

I am using TWebBrowser as an HTML editor. To make life easier, I tried
substituting TEmbeddedWB for TWebBrowser. Most things seem to work fine so
far, with the exception of Undo. With TWebBrowser Ctrl+Z does Undo changes;
with TEmbeddedWB cursor only movement is undone but not text/formatting
changes. This is even true doing it programmatically with either
"IOleCommandTarget.Exec(nil, OLECMDID_UNDO, 0, vaIn, vaOut)" or
"IHTMLDocument2.execCommand('Undo', False, Unassigned)", so it doesn't seem
to be just an issue with keystroke handling.
Any ideas why TEmbeddedWB would disable Undo?
I'm using D5, NT4 SP6, and IE6 SP1.
Thanks
Jim

Did you modify the TEmbeddedWB.Exec method ?
