Hi Nadya,

There may be several reasons. I think the most common are:

- One or more tables/views were not closed because of uncommitted changes.
- Form was not completely released because of dangling references to some objects

To check the last one you may try David Frankenbach's utility in Files Section
file#9466 "ObjRef-finds dangling object references"
