>I have a very strange problem that came up in the last weeks and is happening randomly. Here's the pattern :
>
>- User add a new record
>- The form refresh it's grid to show all records
>- The new record doesn't show
>- The user add the same record
>- The form refresh it's grid to show all records
>- The new record appears in double. This shoudn't be possible because the form validation prevents adding a record that already exist
>
>Somewhere else, a record will appears in double or will not appear at all. If I look at the data directly in the table, everything is okay (record is there and not in double).
>
>This bug appears in many forms, from different tables and for different users. Quitting the application and reopeining it again will resolve the display problem, but it may come back later on.
>
>I really don't understand what's going on here because the bug appears randomly and on forms that haven't been modified in many months/years. I tried reindexing the database and recreate some tables from scratch thinking that it may be a indexing problem, but the problem persist.

>We don't use table ou record buffering.

>I'm starting to think it may be a new incompatibility problem betwen VFP and Windows 10.

>Anyone has any ideas on how to resolve this ?
