Mouse Pointer struck when Grid Header width changes

I am using AW 2.5.3.

I have created a grid with 4 column ( Col1, Col2, Col3,Col4). In one case i am increasing Col1 width,but mouse pointer is attached with the grid. even after i moved to other section of the page, and i came back to grid, it shows the same behavior again.The mouse pointer is changed to a double sided arrow. Only solution is closing it and opening it again.

Thanks

i forgot to mention, this is happing in my application which is using wxWidgets (Mozilla based). also one more observation is when am trying to increase column width beyond my screen, all rows are getting disappeared.
