Thanks for clear my mind.

I posted also problems with Tdatepick doesn´t repainting your canvas after
drop it in a form and clicking on it and another about indicate row in
tib_grid doen´t showing when the dataset becomes empty and next when a
dataset return rows.
I am using D6, win 2000 and IBO 4. I don´t know if this problem exists in
other win versions.
