ALV Grid -- DUMP

Hi All,

I have unique problem.

There is tranaction which display's data in ALV Grid ,

Using some button a new sub screen is called which displays data in ALV grid.

User performs some action in second alv grid, some settings like colors / editable property of this grid are changed.

Now user closed this screen control goes back to grid 1.

User gets a dump now.

But If user performs same steps in another PC he does not get a dump.

Now my question " Is there any link between PC settings and ALV dump ". Both PC have same GUI version.

Thanks for your help in advance.
