Dbdatasource bound matrix and form.freeze bug

Question

I have a UDO, with a child talbe attached to it correctly.
I've build a form to handle the UDO and it's child, in a bound matrix, and everything works fine.
There are 2 comboboxes in the matrix. I want to update a combobox upon selecting in the other combobox. it works fine, yet it looks 'silly' since you can see the focus going to the other cobobox and then return to the original combobox. I thought the Form.Freeze would help me, but it doesnt.
It seems that a dbdatasource-bound-matrix will not show it changes made while being in From.Freeze(True) state. And although changes are not show, they are made, meaning you can click the other combobox and see that the selected value is the one you programmatically selected, but the value inside the box remains as it was before evoking From.Freeze(True).

Hi Avi,
I have created a UDForm for a UDO (Document) with a Matrix for the child table.  I am able to Add the Header with the Child Lines into the DB.  My Problem is that when I need to Update the Document, i call it up, and all the data is shown.  I call "Matrix.AddRow()" and it DUPLICATES the Last line from the matrix into the new row.  So I delete the Duplicated Item Code and retype the new added Item Code and relevent columns.  When I click on "UPDATE" the system says that....
"This Entry Already Exists in the Following Tables " @EB.........
