radgrid problem in IE7 with allowscroll and frozencolumns

[Catalin]

this is my grid definition from aspx page; the columns are generated in the code-behind in page_init

<telerik:RadGrid ID="competenceGrid" runat="server" Width="99%">
       <ClientSettings>
               <Scrolling AllowScroll="True" UseStaticHeaders="True" FrozenColumnsCount="4">
               </Scrolling>
               <ClientEvents OnGridCreated="GridCreated" />
       </ClientSettings>
       <MasterTableView TableLayout="Fixed" Width="100%" Height="100%">
           <RowIndicatorColumn>
               <HeaderStyle Width="20px"></HeaderStyle>
           </RowIndicatorColumn>
           <ExpandCollapseColumn>
               <HeaderStyle Width="20px"></HeaderStyle>
           </ExpandCollapseColumn>
       </MasterTableView>
       <HeaderContextMenu EnableImageSprites="True" CssClass="GridContextMenu GridContextMenu_Default">
       </HeaderContextMenu>
       <ItemStyle HorizontalAlign="Center"/>
       <ActiveItemStyle HorizontalAlign="Center" />
       <AlternatingItemStyle HorizontalAlign="Center" />
       <HeaderStyle Width="160px" Height="75px" />
   </telerik:RadGrid>

Everthing work well in IE8-9, Firefox, but not IE7 where when i horizontal scroll to the end of the right side the first 2 columns from the left which are not  frozen and normally should be displayed are in fact overlaped.
I tried with different combination's for the width value (%) for  the mastertableview  and the radgrid and also in conjunction with tablelayout="fixed|auto". Also the container of the grid have a fixed width in pixels.
Please see the picture attached
Any ideea ?

I come back with an additional note. only the radbuttons in the column headers are overlapping.

Hi Catalin,

I have tried to reproduce the problem you are facing in IE7, but without success. Attached is a small sample that works as expected on my side. Please give it a try and let me know how it goes.

Hi Pavlina,
Thank you for your answer but doesn't help me in any way!
 I looked in your example page, in code behind, from the attached zip file, and i don't saw any buttons in the header of the of the columns... in order correctly reproduce my problem as i described you need to manually create these columns in code behind as GridTemplateColumns and for the HeaderTemplate property of these columns you need to assign an instance of a  custom class that implements the ITemplate interface.Inside this class please add 2 radbuttons.
Otherwise, i can't figured out how can you reproduce my problem and give me an appropriate answer:
