Omnis Studio - Multi-library application

Sorry to learn it is such an old nuisance that has never been fixed ! It
seems to be harmless, but even after you close everything and re-open LibA
alone with its own datafile, all empty slots belonging to LibB are still
* It must be a read/write problem, as suggested by Doug, because the empty
slots are created only for the files which are used to feed the CRB, for
instance merely by browsing through the data.
* Effectively, if we cannot get rid of them, keeping all file formats
together as suggested by Greg could be an option: at least we'll have a
clear and stable situation.
* No more asterisk for current data file in my Omnis Studio, Mike :-)
I will dig "filmode" options (kReadwrite, kReadonly, kMemory, kClosed) and
revert if I make an interesting find.

Thanks to everybody!

That¹s what you call a ³goddamn nuisance² Stephane.
Omnis has been doing that since the beginning.  I don;t think there is
anything you can do about it.

Other than not use file formats.  If you use schema classes and OmnisSQL and
get rid of the file formats, everything ³behaves².
