I have a grid that as relation parent -> child, the grid displays the child table.
This grid as the allowaddnew = .t. , and some times when I add a new record (this Record in is turn create a new set of records in the same table with APPEND BLANK and then replace) a strange thing happen

At the first try all works fine, but then i get an error :
Record is in use by Another user , and this is false of course.

Sometimes when i add a record to the same grid , the grid goes crazy and displays blank squares all over it.

What should i do ??? (I Getting crazy around here!!!)

Thanks in Advance.
