Max Characters RTF2 ActiveX Control

In June '07 I posted a problem that related to the RTF2 control
seeming to truncate large blocks of text at 128K characters (see
original post below).

Stephen Labans kindly provided some advice at the time but the issue
still remains a problem for us. I tried adding a another mail to the
original post but I think it's been closed.

Any help would be very much appreciated.

Original Post:
I'm using Lebans RTF2 control on several forms in my application. The
problem I'm getting is pasting in large blocks of text.
The control seems to truncate the data at approx. 128K characters. Is
this the maximum number of characters the control will handle?
I've tried changing the MaxCharactersAllowed property but it seems
still truncate at 128K. Is there any way to work around this limit?
Any help or suggestions would be greatly appreciated.
