Macro works fine in VBA 6.0 and does not work in VBA 6.3

[Kumar]

I am currently running a macro in Word 2000 and VBA 6.0 which works fine. But
when I try
to run it in Word 2000 with VBA 6.3 on a different computer I am getting an
error.

Error:
Compile error - Method or data member not found

On Line:
Verify.txtResult.Text

Verify uses a text control from RICHTX32.OCX.

It is very peculiar that it deos not work on VBA 6.3. Any idea why this
happens and any resolutions???
