Hi,

>>
i have in my main form's init() do form login to loclicked. when i run main form, i get form login then i'm able to enter user id and password. after i pressed ok in form login, i get error

data environment is already unloaded

error points to do form login to loclicked.

i'm at lost, i don't have any table opened in DE in all forms.

what should i do?
>>

Set the DE.AutoCloseTables to .F. (or look for and get rid of any explicit call to DE.CloseTables()

Regards,
