Grid rendering location shifts

I am using Active Widgets Grid. Sometimes, the grid shifts slightly from its intended location when rendered. In addition, when it is rendered at the right location, you can see a slight movement of the grid while rendering.

I have seen this problem in IE but not Firefox.

I was thinking of using “setControlPosition” parameter of the grid to ensure that it is rendered at the exact location. However, it doesn’t seem like a good solution.

Any comments / suggestions?
