The Database is Read only When it is not (self lockout)

I am in development stage and I have used the security wizard from MS access
for most users I have given Full Access writes.

During testing Something the database gives me message that that “the
database is Readonly� when I am the only user at this point and some how I am
self locking myself.

I am sure that no one else has opened the database , the other interesting
thing is that ( when I get this message I exist from the database and then
check the root file for the database , to my surprise there is no ldb file
created neither for the database nor for the security file for the database ,
and when I try to log in it again gives me “read-only� message.


I have check the properties on the network for the database (and it is not
READONLY)


Some how I am self locking myself the only way I can fix this is by logging
on a different machine and logging out.


Note : The main database on the network has some linked tables to
C:\temp.mdb database


Does anyone know how to resolve this issue


Thanks
