TABLE CONTROL:Scrolling up and down makes the data inconsistent

Hello guys

I have created a Table Control and when I run the program, it displays the data.

When I scroll from left to right or right to left, everything works as expected.

However, when I scroll up and down the top most rows disappear and I can't see the

first few top rows. However this is affecting just the screen and not the actual table.

If I quit and restart the transaction it shows up again normally until I again scroll up and down.

Has anyone seen this problem. Is it a bug or is there some thing I am missing. I would appreciate your feedback.

Thanks

Ram
