Hi HL List.

To Lester and Tony:
I have seen the post on the problem of the grids that disappear in some
cases.

Nearly a week ago I have sent a test, which, at every scroll done in a grid,
reproduce the problem, to Jason.
I think he is working on it to solve the problem.

To Jason:
Maybe the test I have sent you don't work?( or works all fine ? and don't
reproduce the missing of grids?)

HTH
