One work-around I've found so far

[Rene]

Hello,

So far, I've worked around the problem by 'resetting' the contents of the
Textbox in the form's Current event.

The following is not elegant at all, but does the trick.
Essentially, it removes the controlsource, blanks out the control, then
assigns the controlsource back to its original value.

Dim MyControlSource As String
With Me!MyRichTextbox
MyControlSource = .ControlSource
.ControlSource = ""
.Text = ""
.ControlSource = MyControlSource
End With


Still looking for a better solution!
